The side of a trinagular roof is to have the same height h and base b^2 as the side of a trapezodial roof.

Question

a. What is the ratio of the area of the triangular roof to the area of the trapezoidal roof?

(For a triangle, A = 1/2b^2h. For a trapezoid, A = b1 + b2/2h.)

b. Compare the ratio from part of question a to what the ratio will be if b1 is doubled for trapezoidal roof and b2 is doubled for both roofs.
