Question

Find the perimeter of this figure pls

50 added all sides don’t know about the half semi circle

Answer 1

55.1372 m

Explanation:

The composite figure consists of two regular figures

a rectangle of length 16 m and width 9 m

and

a semicircle of diameter d = 9 m

The total length of the outside of the rectangle = 16 + 16 + 9 = 41 m

Circumference of a circle = πd = 9π

Length of the semicircle portion is 1/2 this = 0.5 x 9π = 14.1372 m

Total perimeter = 41 m + 14.1372 m = 55.1372 m
