Area and Perimeter Practice

Front

What is the formula to calculate the area of a rectangle?

Back

Area = Length × Width

Front

What is the formula to calculate the perimeter of a rectangle?

Back

Perimeter = 2(Length + Width)

Front

If a rectangle has a length of 10 units and a width of 5 units, what is its area?

Back

Area = 10 × 5 = 50 square units

Front

If a rectangle has an area of 60 square units and a width of 6 units, what is the length?

Back

Length = Area ÷ Width = 60 ÷ 6 = 10 units

Front

What is the area of a square with a side length of 4 meters?

Back

Area = Side × Side = 4 × 4 = 16 square meters

Front

If the perimeter of a square is 32 meters, what is the length of one side?

Back

Side = Perimeter ÷ 4 = 32 ÷ 4 = 8 meters

Front

What is the relationship between the area and perimeter of a rectangle?

Back

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

Front

If a rectangle has a length of 12 inches and a perimeter of 40 inches, what is the width?

Back

Width = (Perimeter ÷ 2) - Length = (40 ÷ 2) - 12 = 8 inches

Front

What is the area of a rectangle with a length of 7 cm and a width of 3 cm?

Back

Area = 7 × 3 = 21 square centimeters

Front

If a rectangle has a length of 15 feet and a width of 10 feet, what is its perimeter?

Back

Perimeter = 2(15 + 10) = 50 feet
