Answer:

A.
$\text{200 in}^2$ .

Explanation:

We are asked to find the area of the given face of the composite figure.

We can see that the given face consists two squares whose each side in 10 inches.

$\text{Area of square}=a^2$ , where a represents length of each side.

Since the face consists two squares, so area of the given face would be 2 times area of square.

$\text{Area of the given face}=2* a^2$

$\text{Area of the given face}=2*(\text{10 in})^2$

$\text{Area of the given face}=2*\text{100 in}^2$

$\text{Area of the given face}=\text{200 in}^2$

Therefore, the area of the given face is 200 square inches and option A is the correct choice.
