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 a rectangle has a length of 5 feet and a width of 4 feet, what is its area?

Back

Area = 5 ft × 4 ft = 20 square feet.

Front

If a rectangle has a length of 6 inches and a width of 3 inches, what is its perimeter?

Back

Perimeter = 2 × (6 in + 3 in) = 18 inches.

Front

What happens to the area of a rectangle if both the length and width are doubled?

Back

The area becomes four times larger.

Front

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

Back

Area = 4 cm × 4 cm = 16 square centimeters.

Front

What is the formula for the area of a triangle?

Back

Area = 1/2 × base × height.

Front

If a triangle has a base of 10 m and a height of 5 m, what is its area?

Back

Area = 1/2 × 10 m × 5 m = 25 square meters.
