Explanation / Answer

Let the length of base of entrance be c.

tan60 = a/(c/2)

c = 2a/tan60 = 5.77

Let the slant height be h.

sin60 = a/h

h = a/sin60 = 5.77

Area of entrance= E = 0.5*c*a = 0.5*5.77*5 = 14.425

Area of floor = F = b*c = 9*5.77 = 51.93

Area of one side = S = b*h = 9*5.77 = 51.93

Total material required = 2E + F + 2S

= 2(14.425) + 51.93 + 2(51.93)

= 184.64 sq. ft.
