Question

find the area of the figure given to the right. round to the nearest whole number. the area of the figure is question 14, 8.3.b-15 hw score: 57.89%, 11 of 19 points o points: 0 of 1

Explanation:

Step1: Identify the figure as a trapezoid

The figure has two parallel - sides and non - parallel sides. The formula for the area of a trapezoid is $A=\frac{(b_1 + b_2)h}{2}$, where $b_1$ and $b_2$ are the lengths of the parallel sides and $h$ is the height. Here, $b_1=21 + 30+21=72$, $b_2 = 30$, and $h = 9$.

Step2: Substitute values into the formula

$A=\frac{(72 + 30)\times9}{2}=\frac{102\times9}{2}=51\times9 = 459$

Answer:

459
