Answer:
37.55 m
Explanation:
Solution:
Given:
The figure consists of a rectangle, a semicircle, and a quarter circle.
To find:
Total perimeter:
Solution:
In semi circle's part:
The perimeter of the semi-circle = 2π r
here
π = 3.14 and diameter = 10m
therefore, radius(r) = 10/2 = 5m
substituting value.
The perimeter of the semi-circle = 3.14*5=15.7 m
Since the perimeter of a semicircle does not include the perimeter of the diameter.
Included perimeter = 15.7m
Now,

In the rectangle part.
we include a perimeter of CD=2m, AB=2m and CE=5m
included perimeter = 2+2+5=9 m

Again,
The perimeter of the quarter circle =

here
π = 3.14 and diameter = 10m
therefore, radius(r)=5 m
substituting value.
The perimeter of the semi-circle =

the perimeter of a semicircle does not include the perimeter of the diameter. here EF(5m) is also included.
included perimeter = 7.85+5=12.85 m
Now,
Total perimeter = 15.7+9+12.85 =37.55m
Therefore, the Perimeter of the figure is 37.55 m
