Answer 2

Width of the rectangular side of that prism is, 9cm

Explanation:

The formula for Perimeter of pentagonal prism is given by:

`P = 5b`

where

P represents the perimeter of the pentagonal prism and

b is the base length of the pentagonal prism.

Given: Perimeter of pentagonal prism(P) is 45 cm.

Then;

45 = 5b

Divide both sides by 5 we get;

`b = (45)/(5) = 9 cm`

Therefore, the width of the rectangular side of that prism is, 9cm
