the formula for the area of a trapezoid is A=1/2h(b1+b2), where b1 and b2 are both bases and h is height. Find the value of h in terms of A, b1, and b2.
+118723 the formula for the area of a trapezoid is A=1/2h(b1+b2), where b1 and b2 are both bases and h is height. Find the value of h in terms of A, b1, and b2.
\(A=\frac{1}{2}h(b_1+b_2)\\ \mbox{Multiply both sides by 2}\\ 2A=h(b_1+b_2)\\ \mbox{Divide both sides by }(b_1+b_2)\\ \frac{2A}{b_1+b_2}=h\\ h=\frac{2A}{b_1+b_2}\\\)
