Answer:
200 square yards
Step-by-step explanation:
Surface area for this will be the triangle base area x 2 added to the side areas
Side areas are 11 x 5, 11 x 5, and 11 x 6 = 55 + 55 + 66 = 176 square yards
Triangle area = 1/2 (base)(height)
= 1/2(6)(4)
= 1/2(24)
= 12.
But we have two triangles, so 12 x 2 = 24.
Add the sides to the bases: 24 + 176 = 200 square yards for the surface area.
