Grade 3 Math · Area and Perimeter
Build Grade 3 math skills with five 10-question practice tests on area, perimeter, rectangles, squares, formulas, units, and measurement word problems.
These Grade 3 Math practice tests help students measure the inside space and outside distance of rectangles and squares. Students use \(A = l \times w\) for rectangular area and add the side lengths to find perimeter.
First decide whether the problem asks about the space inside a shape or the distance around it. Multiply length by width for area. Add all side lengths for perimeter, and check whether the answer needs square units or regular units.

5. Test
A 10-question Grade 3 Math practice test on rectangle and square area, perimeter, unknown side lengths, units, formulas, and word problems.
Decide whether each problem asks for area or perimeter. Use multiplication for rectangular area, addition for perimeter, and write the answer with the correct unit.
Please select an answer first.
Correct answer: A
The correct answer is .
Area counts the inside space, so multiply length by width.
Please select an answer first.
Correct answer: B
The correct answer is .
A rectangle has two lengths and two widths, so add 2l + 2w.
Please select an answer first.
Correct answer: C
The correct answer is .
Use length \times width: 6 \times 5 = 30 square units.

Correct answer: C
The correct answer is .
The area is 12 \times 6 = 72 square units.
Please select an answer first.
Correct answer: D
The correct answer is .
The perimeter is 10 + 5 + 10 + 5 = 30 units.
Please select an answer first.
Correct answer: A
The correct answer is The 4-by-6 rectangle.
The areas are 24 and 20 square units, so the 4-by-6 rectangle is larger.
Please select an answer first.
Correct answer: B
The correct answer is Area measures inside space; perimeter measures distance around.
Area uses square units for the inside space, while perimeter uses regular units for the boundary.
Multiply the length by the width. Area is written in square units.
Add all four side lengths, or add twice the length and twice the width. Perimeter is written in regular units.
