SOLUTION: this is formula for trapezoid A=h/2(b+c) whats the formula for h? is it : A/2(b+c)=h ? or 2(b+c)/A= h, or b+c/A= h/2 this is from algebra 1 review handout i got not in a boo

You can put this solution on YOUR website!
this is formula for trapezoid A = h/2(b+c) what's the formula for h?
:
Frankly, I don't like any of those answers.
:
%28h%2F2%29%28b%2Bc%29%29 = A
:
If you multiply both sides by 2, you have
h(b+c) = 2A
:
Divide both sides by (b+c) and you have:
h = 2A%2F%28%28b%2Bc%29%29
