7 0

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

To do this, you imagine a vertical (up and down) line moving across your graph from left to right. It should only be touching the line at one point at a time. If it is touching more than one point on the line at a time, the line is not a valid function. The first line and its inverse both pass the test.
