Question

Can someone help me please ?

Answer 1

Hi there!

To start, let's find the area of the bases. Since we're finding the area of two triangles, we don't need to put a 1/2 in front of our equation. This leaves us with 24 x 5 for the area of our bases. Now, we need to find the lateral area. We have two congruent rectangles and one that is different. Using the provided measurements, this leaves us with 2(5 x 13) + 1(20 x 24). Next, we need to add the lateral area to the base area. This leaves us with the surface area, which is 730ft^2. Also, the perimeter of the base is 50ft, the height is 20ft, and the base area is 120ft.

Hope this helps!! :)
