Answer:
The perimeter of triangular prism is 15 inches.
Step-by-step 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.
