Given:

The composite figure consists of two semicircle and a square.

The length of the sides of the square is 2 inches.

The diameter of the semicircle is 2 inches.

We need to determine the area of the composite figure.

Area of the square:

The area of the square can be determined using the formula,


A=s^2

Substituting s = 2, we get;


A=2^2


A=4 \ in^2

Thus, the area of the square is 4 in²

Area of the semicircle:

The area of the semicircle can be determined using the formula,


A=(\pi r^2)/(2)


A=(3.14 * 1^2)/(2)


A=(3.14 )/(2)


A=1.57 \ in^2

Thus, the area of the semicircle is 1.57 in²

Area of the composite figure:

The area of the composite figure can be determined by adding the area of the square and the area of the two semicircles.

Thus, we have;


Area=4+1.57+1.57


Area = 7.14 \ in^2

Thus, the area of the composite figure is 7.14 in²

Hence, Option c is the correct answer.
