V125BC [204]

Answer:

Approximately 201 squared inches.

Step-by-step explanation:

So, the composite figure is made up of a square and a semi-circle. The square has side lengths of 12 and the semi-circle has a radius of 6.

The total area of the figure would be the area of the square plus the area of the semi-circle. Thus, find the area of each individual figure.

Square:

The area of a square is given by:

$A=l^2$

Where l is the side length.

Substitute 12 for l:

$A=(12)^2\\A=144\text{ in}^2$

So the square is 144 square inches.

Semi-circle:

The area of a semi-circle is given by:

$A=\frac{1}{2}\pi r^2$

Substitute 6 for r and 3.14 for π:

$A=\frac{1}{2}(3.14)(6)^2\\ A=56.52$

Therefore, the total area is:

$TA=144+56.52\\TA=200.52\text{ in}^2\approx201\text{ in}^2$
