Answer:

390m^2

Explanation:

The Surface Area of a triangular prism is L(s1 + s2 + s3) + 2*base area

a = 5m

b = 12m

c = 13m

L = 11m

First, we need to find the base area...

base area = (a*b)/2

(5*12)/2 = 30 m^2

Next, find the surface area

A = 11(5 + 12 +13) + 2*30 = 390 m^2

PLEASE RATE!! I hope this helps!!
