Back

Perimeter measures the distance around a shape, while area measures the space inside a shape.

Front

If a rectangle has a length of 5 cm and a width of 4 cm, what is its area?

Back

A = length × width = 5 cm × 4 cm = 20 cm².

Front

If a rectangle has a length of 10 in and a width of 3 in, what is its perimeter?

Back

P = 2(length + width) = 2(10 in + 3 in) = 26 in.
