Question

find the area of this figure
4 cm
5 cm
9 cm
36 square cm
32.5 square cm
65 square cm
45 square cm

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

Here, $a = 4$ cm, $b = 9$ cm, and $h = 5$ cm.

Step3: Substitute values into formula

$A=\frac{(4 + 9)\times5}{2}=\frac{13\times5}{2}=\frac{65}{2}=32.5$ square cm.

Answer:

32.5 square cm
