Question

Which correctly shows the area formula for a trapezoid, A=12h(b1+b2), rearranged for the quantity of interest h?

Answer 1

To rearrange the area formula for the quantity of interest h, you would divide both sides of the equation by 12(b1+b2):

A = 12h(b1+b2)

Dividing by 12(b1+b2) on both sides:

A / (12(b1+b2)) = h

Therefore, the correct formula rearranged for the quantity of interest h is:

h = A / (12(b1+b2))
