Front

How do you calculate the area of a rectangle?

Back

Area = length × width.

Front

How do you calculate the perimeter of a rectangle?

Back

Perimeter = 2 × (length + width).

Front

If the length of a rectangle is doubled, what happens to the area?

Back

The area becomes four times larger.

Front

If the width of a rectangle is halved, what happens to the area?

Back

The area is also halved.

Front

What are the dimensions of a rectangle with an area of 48 square feet and a length of 8 feet?

Back

Width = Area ÷ Length = 48 ÷ 8 = 6 feet.

Front

What is the perimeter of a rectangle with a length of 10 feet and a width of 5 feet?

Back

Perimeter = 2 × (10 + 5) = 30 feet.

Front

If a square has a side length of 4 inches, what is its area?

Back

Area = side × side = 4 × 4 = 16 square inches.

Front

What is the area of a triangle with a base of 6 inches and a height of 4 inches?

Back

Area = 1/2 × base × height = 1/2 × 6 × 4 = 12 square inches.
