Answer:
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
