-The Area $A$ Of a Trapezoid with Bases $b$ And $B$ And Height

Solve.
-The area $A$ of a trapezoid with bases $b$ and $B$ and height $h$ is given by the formula $A = \frac { 1 } { 2 } b h + \frac { 1 } { 2 } B h . W r i t e$ an equivalent equation by factoring the expression $\frac { 1 } { 2 } b h + \frac { 1 } { 2 } \mathrm { Bh }$ .

A) $\mathrm { A } = 2 ( \mathrm {~b} + \mathrm { B } ) \mathrm { h }$
B) $A = \frac { 1 } { 2 } ( b + B + h )$
C) $A = \frac { 1 } { 2 } ( b + B ) h$
D) $\mathrm { A } = ( \mathrm { b } + \mathrm { B } ) \mathrm { h }$
