Answer 1

Find the lateral area of the right triangular prism.

Answer 2

La=Ph=(12)(3)=36m

Answer 3

Perimeter of the triangular base = 3 + 4 + 5 = 12m (The third side is 5m because sqrt(3^2 + 4^2) = sqrt(25) = 5).
Height = 6m
Lateral surface area = perimeter of base * height = 12m * 6m = 72 m^2.
