Question

find the area. 60 cm 432 cm sq 108 cm sq 216 cm sq

Explanation:

Step1: Recall trapezoid area formula

The formula for the area of a trapezoid is $A=\frac{(a + b)h}{2}$, where $a$ and $b$ are the lengths of the parallel - sides and $h$ is the height. Here, $a = 14$ cm, $b = 22$ cm, and $h = 12$ cm.

Step2: Substitute values into formula

$A=\frac{(14 + 22)\times12}{2}$. First, calculate the sum of the parallel sides: $14+22 = 36$ cm. Then, multiply by the height: $36\times12=432$ $cm^2$. Finally, divide by 2: $\frac{432}{2}=216$ $cm^2$.

Answer:

D. 216 cm sq
