Answer:
P=48.56ft
Step-by-step explanation:
perimeter of the rectangle is:
P=2(l+b)
=2(10+8)
=2(18)
=36ft
perimeter of the semi-circle is:
C=3.14*8
=25.12ft
since its half the circle we divide the big perimeter by two,therefore its 12.56ft.
The perimeter of the whole figure is by adding the two perimeters
therefore: 36+12.56
48.56ft
