area and perimeter

Front

What is the perimeter of a rectangle?

Back

The perimeter of a rectangle is the total distance around the rectangle, calculated as 2 times the length plus 2 times the width (P = 2L + 2W).

Front

How do you find the area of a rectangle?

Back

The area of a rectangle is found by multiplying the length by the width (Area = Length x Width).

Front

If a rectangle has a length of 10 ft and a width of 5 ft, what is its perimeter?

Back

The perimeter is 30 ft (P = 2(10) + 2(5) = 30).

Front

If a rectangle has a length of 8 cm and a width of 3 cm, what is its area?

Back

The area is 24 sq cm (Area = 8 x 3 = 24).

Front

What is the formula for finding the area of a rectangle?

Back

Area = Length x Width.

Front

What is the formula for finding the perimeter of a rectangle?

Back

Perimeter = 2(Length + Width).

Front

If a rectangle has an area of 48 sq ft and a width of 6 ft, what is the length?

Back

The length is 8 ft (Length = Area / Width = 48 / 6 = 8).

Front

What is the perimeter of a rectangle with a length of 12 in and a width of 4 in?

Back

The perimeter is 32 in (P = 2(12) + 2(4) = 32).

Front

If the perimeter of a rectangle is 50 cm and the length is 15 cm, what is the width?

Back

The width is 10 cm (P = 2L + 2W; 50 = 2(15) + 2W; 50 = 30 + 2W; 20 = 2W; W = 10).

Front

What is the area of a rectangle with a length of 7 m and a width of 2 m?

Back

The area is 14 sq m (Area = 7 x 2 = 14).
