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 .
The perimeter is 2 \times 10 + 2 \times 6 = 32 \text{units}.
Please select an answer first.
Correct answer: B
The correct answer is .
Multiply the side length by 4: 4 \times 9 = 36 \text{units}.
Please select an answer first.
Correct answer: C
The correct answer is .
Add 12 + 2 + 12 + 2 to get 28 \text{units}.
Please select an answer first.
Correct answer: D
The correct answer is .
The perimeter is 11 + 3 + 11 + 3 = 28 \text{units}.
Please select an answer first.
Correct answer: A
The correct answer is .
A square has four equal sides, so 4 \times 6 = 24 \text{units}.
Please select an answer first.
Correct answer: B
The correct answer is The distance around the shape.
Perimeter is the total distance around the outside boundary of a shape.
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.
