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.

Correct answer: A
The correct answer is .
Divide 42 square units by 6 units: the length is 7 units.
Please select an answer first.
Correct answer: B
The correct answer is .
The two length sides total 18 units. The remaining 12 units make two widths, so each width is 6 units.

Correct answer: D
The correct answer is .
The two length sides use 20 units, leaving 6 units for two widths. Each width is 3 units.
Please select an answer first.
Correct answer: A
The correct answer is .
Seven times seven is 49, so each side is 7 units.
Please select an answer first.
Correct answer: B
The correct answer is .
Divide 54 by 9 to find the width: 6 units.
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.
