Help me find the surface area
lesya [120]

Step-by-step explanation:

it looks like this is a regular (right) triangular prism with 3 equal side areas and one bottom area.

the surface area of the pyramid is the sum of all 4 of these areas.

all these areas are triangles.

the area of a triangle is

baseline × height / 2

in our case

1 side area is 6×8.2/2 = 3×8.2 = 24.6 yd²

all 3 side areas together are 24.6×3 = 73.8 yd²

the bottom triangle is

6×5.2/2 = 3×5.2 = 15.6 yd²

so, the total surface area is

73.8 + 15.6 = 89.4 yd²
