Find the appropriate perimeter of the figure below

yanalaym [24]

Answer:

55.7 in.

Step-by-step explanation:

I assume the figure is a rectangle and a half circle.

The three sides of the rectangle that need to be added toward the perimeter measure 15 in., 10 in., and 15 in.

Then you need the circumference of the half circle which has a 10-inch diameter.

circumference = (pi)d

circumference = 3.14 * 10 in. = 31.4 in.

We only need half the circumference, so we have 31.4 in./2 = 15.7 in.

Now we add the three sides of the rectangle listed above and the circumference of the half circle.

perimeter = 15 in. + 10 in. + 15 in. + 15.7 in.

perimeter = 55.7 in.
