Area and Perimeter

Front

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

Back

A = l x w (Area = length x width)

Front

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

Back

P = 2 x (l + w) (Perimeter = 2 x (length + width))

Front

What is the area of a rectangle with a length of 5 cm and a width of 3 cm?

Back

A = 5 x 3 = 15 square cm

Front

What is the perimeter of a rectangle with a length of 10 cm and a width of 4 cm?

Back

P = 2 x (10 + 4) = 28 cm

Front

If a rectangle has an area of 24 square cm and a width of 4 cm, what is its length?

Back

l = A / w = 24 / 4 = 6 cm

Front

What is the area of a rectangle that measures 8 cm in length and 4 cm in width?

Back

A = 8 x 4 = 32 square cm

Front

What is the perimeter of a rectangle that measures 6 cm in length and 2 cm in width?

Back

P = 2 x (6 + 2) = 16 cm

Front

Calculate the area of a rectangle with a length of 10 cm and a width of 2 cm.

Back

A = 10 x 2 = 20 square cm

Front

If the length of a rectangle is doubled, how does that affect the area?

Back

The area also doubles if the width remains the same.

Front

What is the area of a rectangle with a length of 12 cm and a width of 5 cm?

Back

A = 12 x 5 = 60 square cm
