Judah Meza · Answer 1

First, determine the perimeter of the base by the doubling the sum of the length and the width. That is,

P = 2 (a + b)

Substituting the known values,

P = 2 (5 in + 3 in) = 16 in

Then, multiply the calculated value by the height to solve for the lateral area.

LA = (16 in) (2 in) = 32 in²

Thus, the answer to this item is letter A.
