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: D
The correct answer is .
Multiply 9 by 3: the rectangle covers 27 \text{square units}.
Please select an answer first.
Correct answer: A
The correct answer is .
A square has equal sides, so its area is 6 \times 6 = 36 \text{square units}.

Correct answer: B
The correct answer is .
Multiply 10 \times 5 to get 50 \text{square units}.
Please select an answer first.
Correct answer: C
The correct answer is .
The area is 12 \times 2 = 24 \text{square units}.
Please select an answer first.
Correct answer: D
The correct answer is .
Multiply the two side lengths: 11 \times 3 = 33 \text{square units}.
Please select an answer first.
Correct answer: A
The correct answer is .
The order of the factors does not matter: 4 \times 9 = 36 \text{square units}.
Please select an answer first.
Correct answer: B
The correct answer is The space inside the shape.
Area measures the space inside a shape and is written in square 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.
