Work Step by Step
$A=bh$ The question asks us to calculate the area by multiplying the measurement of the base by the measurement of the height. The length of the base equals 12m and the length of the height equals 9m. We then have to input 9 and 12 into the formula to find the answer. This means: $b=12$ $h=9$ $A=12(9)$ $A=108m^2$ The area of the parallelogram is $108m^2$.
