Question

The formula for the area of a trapezoid is A=1/2h(a+b), where h represents the height and a and b represent the length of the bases. Solve for h.

Answer 1

\(\large A=\frac{1}{2}h(a+b) \)
\(\large 2A=h(a+b) \) multiply 2 to both sides;
\(\large \frac{2A}{a+b}=h \) divide both sides by a+b

Answer 2

where did you get 2 from?

Answer 3

cause the original function is A=1/2h(a+b), then u multiply both sides with 2...then u get
2A=1/2*2*h(a+b)
