Which correctly shows the area formula for a trapezoid, A=1/2h (b1+b2), rearranged for the quantity of interest h?

Answer 1

To rearrange the formula, we need to isolate the variable 'h' on one side of the equation. The correct rearrangement of the area formula for a trapezoid is:

A = (1/2)h(b1 + b2)

First, we can multiply both sides of the equation by 2 to eliminate the fraction:

2A = h(b1 + b2)

Then, to solve for 'h,' we can divide both sides of the equation by (b1 + b2):

h = 2A / (b1 + b2)

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

h = 2A / (b1 + b2)
