120 sq in, 150 sq in, 720 sq in.

Solution:

Given figure represents a pentagonal prism.

Perimeter of the base = 20 inches

Height of the prism, h = 6 inches.

We have to find the lateral area.

Lateral area = perimeter of base × height

= 20 × 6

= 120 square inches.

Therefore, the lateral area is 120 square inches.

Find the lateral area of the prism.

Summary:

The lateral area of the prism is 120 square inches.
