Question

find the area: 8 yd 9 yd 11 yd 57 square yards 114 square yards 88 square yards 66 square yards

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.

Step2: Identify values of $a$, $b$ and $h$

Here, $a = 8$ yd, $b = 11$ yd and $h=6$ yd.

Step3: Substitute values into formula

$A=\frac{(8 + 11)\times6}{2}=\frac{19\times6}{2}$.

Step4: Calculate the result

First, $19\times6 = 114$, then $\frac{114}{2}=57$ square yards.

Answer:

57 square yards
