Question

Find the perimeter and total area of the composite shape shown below. All measurements are given in inches. Use t = 3.14 in

Answer 1

Answer:  C) Perimeter = 46.28

Step-by-step explanation:

The lengths of the sides on the bottom half of the shape are given as :

left = 10, bottom = 20, right = 10 = 40.

Need to find the perimeter of the semicircle at the top of the shape.

Perimeter of a circle is the Circumference = 2πr

So the perimeter of a semicircle = πr

                                                             = 3.14(2)

                                                             = 6.28

Add up the lengths of the left, bottom, right, and top: 40 + 6.28 = 46.28

Since there is only one option for Perimeter = 46.28, there is no need to solve for the Area.
