Question

The formula for the area of a trapezoid with altitude k and bases m and n is . Solve for m

Answer 1

A = ((m+n)/2)*k

Answer 2

1/2(k)(m+n)=A
2A/k=m+n
m=2A/k -n

Answer 3

The formula for the area of a trapezoid with altitude k and bases m and n is \[a=\left(\begin{matrix}k \\ 2\end{matrix}\right) (m+n)\]
. Solve for m
