Answer:
\(m=A\times\frac{2}{k}-n\)
Step-by-step explanation:
Given : The formula for the area of a trapezoid with altitude k and bases m and n is \(A=\frac{k}{2}(m+n)\)
We have solve for m .
Consider the given formula \(A=\frac{k}{2}(m+n)\)
Multiply both side by \(\frac{2}{k}\), we have,
\(A\times\frac{2}{k}=m+n\)
Now subtract n both side, we have,
\(A\times\frac{2}{k}-n=m\)
Thus, \(m=A\times\frac{2}{k}-n\)
