- To determine the perimeter of the base, consider that the length is 5 in and the width is the same as the width of the top face of the prism, that is, 2 in. Then, the perimeters is:

P = 2l + 2w

w = 2 in

l = 5 in

P = 2(5 in) + 2(2 in)

P = 10 in + 4 in

P = 14 in

- The height of the doorstop is 1.2 in

- The area of the base is:

A = wl

A = (2 in)(5 in)

A = 10 in²
