Answer:
Step-by-step explanation:
Front/Back
A = L*W
L = 8 in
w = 5
Area = 8 * 5 = 40 in^2
Total area = 2 * 40 = 80 in^2
Left/Right
Area = L*w
L = 15 in
w = 5
Area = 15 * 5 = 75
Total Area = 2 * 75 = 150
Triangles Front/Back
Area = 1/2 * b * h
b = 8
h = 7
Area = 1/2 * 8*7
Area = 28
Total Area = 2 * 28 = 56
Roof Left Right
Use the Pythagorean Theorem to get the slant
a = 7
b = 1/2 * 8 = 4
c = ?
c^2 = a^2 + b^2
c^2 = 7^2 + 4^2
c^2 = 49 + 16
c^2 = 65
sqrt(c^2) = sqrt(65)
c = 8.06
Area = L * slant
L = 15
slant = 8.06
Area = 15 * 8.06
Area = 120.9
Total area = 2 * 120.9
Total area = 241.8
Total Area = 241.8 +56 + 150 + 80
Total Area = 527.8
