The formula for the area of a trapezold with altitude k and bases m and n is A=k/2(m+n)
Ghella [55]

Answer:

m=\frac{2A-kn}{k}

Hence, option C is true.

Step-by-step explanation:

Given the expression

A=\frac{k}{2}\left(m+n\right)

Solving for 'm'

A=\frac{k}{2}\left(m+n\right)

Flip the equation

\frac{k}{2}\left(m+n\right)=A

Expanding by applying the distributive law: a\left(b+c\right)=ab+ac

\frac{1}{2}km+\frac{1}{2}kn=A

Add (-1)/2 × kn to both sides

\frac{1}{2}km+\frac{1}{2}kn+\left(-\frac{1}{2}kn\right)=\left(-\frac{1}{2}kn\right)+A

simplify

\frac{1}{2}km=-\frac{1}{2}kn+A

Divide both sides by k/2

\frac{\frac{1}{2}km}{\frac{k}{2}}=\frac{-\frac{1}{2}kn+A}{\frac{k}{2}}

m=\frac{2A-kn}{k}

Therefore,

m=\frac{2A-kn}{k}

Hence, option C is true.
