Step-by-step explanation:
p = 2w
p = total pieces = 16
then putting value in p = 2w

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:

Where l is the side length.
Substitute 12 for l:

So the square is 144 square inches.
Semi-circle:
The area of a semi-circle is given by:

Substitute 6 for r and 3.14 for π:

Therefore, the total area is:
