Area and Perimeter of Rectangles

Front

What is the formula for calculating 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 perimeter?

Back

Perimeter = 2 × (10 + 5) = 30 units

Front

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

Back

Area = length × width

Front

If a rectangle has a length of 4 units and a width of 3 units, what is its area?

Back

Area = 4 × 3 = 12 square units

Front

What does 'perimeter' mean?

Back

Perimeter is the total distance around the outside of a shape.

Front

What does 'area' mean?

Back

Area is the amount of space inside a shape.

Front

If the perimeter of a rectangle is 26 units and the length is 8 units, what is the width?

Back

Width = (Perimeter/2) - Length = (26/2) - 8 = 5 units

Front

If a rectangle has a perimeter of 22 units and a width of 6 units, what is the length?

Back

Length = (Perimeter/2) - Width = (22/2) - 6 = 5 units

Front

What is the perimeter of a rectangle with a length of 7 units and a width of 2 units?

Back

Perimeter = 2 × (7 + 2) = 18 units

Front

What is the area of a rectangle with a length of 5 units and a width of 4 units?

Back

Area = 5 × 4 = 20 square units
