Give your answer to two decimal places.

Answer 1

So, the perimeter of the shape is 48 cm.

Explanation:

To calculate the perimeter of the shape with sides of 18 cm and 6 cm, you simply need to add the lengths of all the sides together. In this case, it's a simple rectangular shape:

P = 2(18 cm) + 2(6 cm)

P = 36 cm + 12 cm

P = 48 cm
