Step-by-step explanation:
The perimeter of the circular part of the sports exhibition can be found with the formula r.The equation is halved from the 2r as it is half a circle.
perimeter of circular part=17
Perimeter of the sports exhibition:
(4000/100)+10+10+68+33+17+34+(700/100)
=202+17
=255m(nearest whole number)
For the area, find the total area of the representive shapes
The two rectangles:10*40+68*33
=2644
The area of the semi circle (:r^2)/2
=17*17*/2
=144.5
Total area:
2644+144.5
=3098m^2(nearest whole number)
