The given figure is form by a semi circle and a rectangle
In the given figure, the diamter of the semi circle is 7 ft, Radius = 3.5 cm
The general expression for the perimeter of the circle is :
[tex]\text{Perimeter of Circle=2}\Pi Radius[/tex]then for the semi circle :
[tex]\text{Perimeter of Semicircle=}\Pi radius[/tex]Substitute the value of r = 3.5 cm
[tex]\begin{gathered} \text{Perimeter of Semicircle=}\Pi radius \\ \text{Perimeter of Semicircle=3.14}\times3.5 \\ \text{Perimeter of Semicircle= 10.99 ft}^2 \end{gathered}[/tex]Now, for the rectangle
The perimeter of rectangle = 2(Length + Breadth)
In the given figure, we have Length = 14 ft and breadth = 7ft
[tex]\begin{gathered} \text{ Perimeter of the given rectangle=2(14+7)} \\ \text{Perimeter of the given rectangle=2(21)} \\ \text{Perimeter of the given rectangle=}42\text{ ft} \end{gathered}[/tex]
