Question

I really need some good help

Answer 1

15

Explanation:

The lateral surface area is the perimeter of the base times the height, so the perimeter is 195/13 = 15.

Answer 2

The perimeter of triangular prism is 15 inches.

Explanation:

We have given the lateral surface area and height of a triangular prism.

Height = h = 13 inches and L.S.A = 195 in²

We have to find the perimeter of triangular prism.

The formula to find the L.S.A is :

L.S.A = P×h where P is the perimeter and h is the height of triangular prism.

putting given values in above formula,we have

195 = P×13

P = 195÷13

P = 15 inches

Hence, the perimeter of triangular prism is 15 inches.
