Front

What is the formula for the perimeter of a rectangle?

Back

Perimeter = 2 × (length + width)

Front

If a rectangle has a length of 5 feet and a width of 3 feet, what is its perimeter?

Back

Perimeter = 2 × (5 + 3) = 16 feet

Front

What is the formula for the area of a rectangle?

Back

Area = length × width

Front

If a rectangle has a length of 10 feet and a width of 2 feet, what is its area?

Back

Area = 10 × 2 = 20 square feet

Front

What is the relationship between area and perimeter?

Back

Area measures the space inside a shape, while perimeter measures the distance around it.

Front

If the perimeter of a rectangle is 20 feet and the width is 4 feet, what is the length?

Back

Length = (Perimeter/2) - Width = (20/2) - 4 = 6 feet

Front

What is the width of a rectangle if the area is 30 square feet and the length is 6 feet?

Back

Width = Area / Length = 30 / 6 = 5 feet

Front

If a rectangle has a perimeter of 24 cm and a length of 8 cm, what is the width?

Back

Width = (Perimeter/2) - Length = (24/2) - 8 = 4 cm

Front

What is the area of a rectangle with a length of 12 feet and a width of 4 feet?

Back

Area = 12 × 4 = 48 square feet

Front

If the area of a rectangle is 56 square feet and the width is 7 feet, what is the length?

Back

Length = Area / Width = 56 / 7 = 8 feet
