Answer:
1,120 yd²
Step-by-step explanation:
Surface area of triangular prism = 2(BA) + P*H
✔️Triangular base area (BA) = ½bh
b = 15 yd
h = 8 yd
Base area (BA) = ½*8*15 = 60 yd²
✔️Perimeter of the base (P) = 17 + 15 + 8 = 40 yd
✔️Height or lenghtbor prism (P) = 25 yd
✔️Surface area = 2(60) + 40*25 = 120 + 1,000 = 1,120 yd²
