Help please, Find the perimeter of the figure to the nearest hundredth.

Step-by-step explanation:

Since there are two half circles, we just need to work to find the perimeter of a whole circle. The formula for the perimeter (circumference) of a circle:

We need to know the radius to find the circumference. By studying the figure, we know that the length of the entire shape is 12 ft. We also know that on either side of the half circles, the length is 3 ft. If we divide 12 by 3, we see that the total length of 12 ft can be broken into 4 parts, each measuring 3 ft. The radius is half the diameter, so the radius is 3. Insert the values:

Simplify:

Now add the values of the exposed parts of the rectangle:

The perimeter is 36.84.

:Done
