Question

The formula for the area of a trapezoid is A = ½h(b₁ + b₂), where h is the height

and b₁ and b2 are the two bases. Rewrite the formula to solve for h in terms of A, b₁
and b₂.

Answer 1

Explanation:

that means that we need to transform the equation so that we get a form

h = ...

A = ½h(b1 + b2) | multiply both sides by 2

2A = h(b1 + b2) | divide both sides by (b1 + b2)

2A/(b1 + b2) = h

that's it.
