Grade 4 Area and Perimeter Practice Test

Build Grade 4 Math skills with five 10-question practice tests on area, perimeter, rectangles, squares, missing side lengths, and measurement word problems.

Area and Perimeter Practice Tests

These Grade 4 Math practice tests help students find the area and perimeter of rectangles and squares. Students also solve missing-dimension problems and apply measurement formulas to gardens, rooms, frames, rugs, and playgrounds.

Skills covered

  • Finding the area of rectangles and squares
  • Finding the perimeter of rectangles and squares
  • Solving for missing side lengths
  • Choosing square units for area
  • Applying area and perimeter to word problems
  • Comparing shapes by area or perimeter

How to use these practice tests

Area measures the space inside a shape. For a rectangle, use length times width. Perimeter measures the distance around a shape, so add all side lengths or use 2 times the length plus 2 times the width. Area uses square units, while perimeter uses regular units.

1. QuestionMultiple choice

A rectangle has area 24 square units and width 44 units. What is its length?

Please select an answer first.

Correct answer: A

The correct answer is 6 units.

  1. Choose the formula: Use length times width for area and add all side lengths for perimeter.
  2. Substitute the measurements: Length = area ÷ width = 24 ÷ 4 = 6 units.
  3. Include the correct unit: The correct choice is 6 units.

Length = area ÷ width = 24 ÷ 4 = 6 units.

2. QuestionMultiple choice

A rectangle has perimeter 20 units and length 66 units. What is its width?

Please select an answer first.

Correct answer: B

The correct answer is 4 units.

  1. Choose the formula: Use length times width for area and add all side lengths for perimeter.
  2. Substitute the measurements: Half of the perimeter is 10, and 10 − 6 = 4 units for the width.
  3. Include the correct unit: The correct choice is 4 units.

Half of the perimeter is 10, and 10 − 6 = 4 units for the width.

3. QuestionMultiple choice

A square has area 49 square units. What is the length of one side?

Please select an answer first.

Correct answer: C

The correct answer is 7 units.

  1. Choose the formula: Use length times width for area and add all side lengths for perimeter.
  2. Substitute the measurements: Seven times seven equals 49, so each side is 7 units.
  3. Include the correct unit: The correct choice is 7 units.

Seven times seven equals 49, so each side is 7 units.

4. QuestionMultiple choice

A square has perimeter 32 units. What is the length of one side?

Please select an answer first.

Correct answer: D

The correct answer is 8 units.

  1. Choose the formula: Use length times width for area and add all side lengths for perimeter.
  2. Substitute the measurements: A square has four equal sides: 32 ÷ 4 = 8 units.
  3. Include the correct unit: The correct choice is 8 units.

A square has four equal sides: 32 ÷ 4 = 8 units.

5. QuestionMultiple choice

A rectangle has area 35 square units and length 77 units. What is its width?

Please select an answer first.

Correct answer: A

The correct answer is 5 units.

  1. Choose the formula: Use length times width for area and add all side lengths for perimeter.
  2. Substitute the measurements: Width = area ÷ length = 35 ÷ 7 = 5 units.
  3. Include the correct unit: The correct choice is 5 units.

Width = area ÷ length = 35 ÷ 7 = 5 units.

6. QuestionMultiple choice

A rectangle has perimeter 30 units and length 1010 units. What is its width?

Please select an answer first.

Correct answer: B

The correct answer is 5 units.

  1. Choose the formula: Use length times width for area and add all side lengths for perimeter.
  2. Substitute the measurements: Half of 30 is 15, and 15 − 10 = 5 units.
  3. Include the correct unit: The correct choice is 5 units.

Half of 30 is 15, and 15 − 10 = 5 units.

7. QuestionMultiple choice

A rectangle has area 48 square units and width 66 units. What is its length?

Please select an answer first.

Correct answer: C

The correct answer is 8 units.

  1. Choose the formula: Use length times width for area and add all side lengths for perimeter.
  2. Substitute the measurements: Length = 48 ÷ 6 = 8 units.
  3. Include the correct unit: The correct choice is 8 units.

Length = 48 ÷ 6 = 8 units.

8. QuestionMultiple choice

A rectangle has perimeter 36 units and width 88 units. What is its length?

Please select an answer first.

Correct answer: D

The correct answer is 10 units.

  1. Choose the formula: Use length times width for area and add all side lengths for perimeter.
  2. Substitute the measurements: Half of 36 is 18, and 18 − 8 = 10 units.
  3. Include the correct unit: The correct choice is 10 units.

Half of 36 is 18, and 18 − 8 = 10 units.

9. QuestionMultiple choice

A square has area 64 square units. What is the length of one side?

Please select an answer first.

Correct answer: A

The correct answer is 8 units.

  1. Choose the formula: Use length times width for area and add all side lengths for perimeter.
  2. Substitute the measurements: Eight times eight equals 64, so the side length is 8 units.
  3. Include the correct unit: The correct choice is 8 units.

Eight times eight equals 64, so the side length is 8 units.

10. QuestionMultiple choice

A rectangle is 99 units long and has area 45 square units. What is its width?

Please select an answer first.

Correct answer: B

The correct answer is 5 units.

  1. Choose the formula: Use length times width for area and add all side lengths for perimeter.
  2. Substitute the measurements: Width = 45 ÷ 9 = 5 units.
  3. Include the correct unit: The correct choice is 5 units.

Width = 45 ÷ 9 = 5 units.

Frequently asked questions about Grade 4 Area and Perimeter

What is the difference between area and perimeter?

Area measures the space inside a shape and uses square units. Perimeter measures the distance around a shape and uses regular length units.

How do you find the area of a rectangle?

Multiply the length by the width. For example, a 6-by-4 rectangle has an area of 24 square units.
