1/2 h (b1 + b2) solve for h help!?!?!?

Question

1/2 h (b1 + b2) solve for h help!?!?!?

Answer 1

A = 1/2 h (b1 + b2)

<--- you need an equation, not an expression, to solve

<--- I took an educated guess as to what the equation should be :-)

h = 2A (b1 + b2)

Answer 2

Area = (1/2)h * (b1+b2)

Move everything, so that h is alone on one side

2*area = h*(b1+b2)

(2*area) / (b1+b2) = h

This is called isolating the variable

Answer 3

It can't be done. There is nothing to solve for.

I think you left out the equals sign and whatever goes to the right of it.
