Question

Find the Perimeter of the figure below, composed of a rectangle and a semicircle.

Round to the nearest tenths place.

Answer 1

53.7

Explanation:

Rectangle: lenth = 14, width = 2 * 5 = 10

perimeter of reactangle (3 sides) = 14 + 10 + 14 = 38

perimeter of semicircle = π * 5 = 3.14 * 5 = 15.7

Total perimeter = 38 + 15.7 = 53.7

Answer 2

Explanation:

Rectangle:

Length = 14 units

Width = diameter of the semicircle = 2*5 = 10 units

Circumference of circle = πr = 3.14 * 5 = 15.7 units

Perimeter of the figure = 14 + 10 + 14 + 15.7 = 53.7 units
