Answer 1

Understanding how to solve...

The base of each triangle is 11 ft, and the height of it is 9 ft.

And then, there are 4 of these triangles. So, as we know, when we do the formula for finding one triangle, we do $SA=\frac{1}{2} *B*H$. But if we have to do it for 2, then we will do... $SA = B*H$, and applying that same trick, if we have to do it for 4 of them, we will do $SA =2*B*H$

Finding answer:

B = 11

H = 9.53

$SA = 2*B*H\\=2*11*9.53\\=2*104.83\\=209.66$

Answer:

209.66ft² of wrapping paper was used
