Triangle formula to find surface area base x height divided by 2. Rectangles. Base x heights.
The two triangles equal
16x15 then divide the answer by 2. Then times the one triangle by two. P.S. This is instructions for one triangle. Times the surface area of one triangle by two.
The bottom rectangle
16 x 10. That’s it
The two side rectangles
17 x 10. They times the answer you get for 17 x 10 by two.
Add all the surface areas together, and their is your answer.
