Question

1. answer: ________

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, $a = 5$ in, $b=10$ in, and $h = 7$ in.

Step2: Substitute values into formula

$A=\frac{(5 + 10)\times7}{2}=\frac{15\times7}{2}=\frac{105}{2}=52.5$ square - inches.

Answer:

$52.5$ square inches
