A 12 ft by 15 ft rectangular swimming pool has a 4 ft wide no slip surface around it. What is the outer perimeter of the no slip surface? (Draw a picture to help you)(1 point)

Answer 1

The outer perimeter of the no-slip surface is formed by two lengths and two widths of the pool, as shown in the picture:

The two lengths of the pool are 15 ft each, and the two widths are 12 ft each. Therefore, the outer perimeter of the no-slip surface is:

Perimeter = 2(15 ft) + 2(12 ft)
Perimeter = 30 ft + 24 ft
Perimeter = 54 ft

So, the outer perimeter of the no-slip surface is 54 ft.
