Find the lateral area of the square pyramid.

Answer 1

352 m^2

Explanation:

Each of the four congruent triangular faces has an area that is half the product of the base edge length and the slant height:

A = 1/2·bh = 1/2·(8 m)(22 m) = 88 m^2

Then the total lateral area is 4 times this:

LA = 4·88 m^2 = 352 m^2
