I think it's 24

132 : 11= 12
12 x 2= 24

The formula in solving the lateral area of an equilateral triangular prism is:
Lateral Surface Area = P (perimeter) * H (height)
Lateral SA is given which is equal to 132 meters and the height is also given which is equal to 11 meters.
132=P*H
132=P*11
P=132/11
Perimeter=12 units


The base is an equilateral triangle, therefore the side length is jus Perimeter divided by 3.
Side length=P/3
Side length=12 units/3
Side length = 4 units

The answer is 4.
