Answer:

Explanation:
The Length of fence needed will be the sum of the Length of the two rectangles and the two semicircles.
Perimeter of a Semicircle =

Perimeter of Two Semicircles

Radius of the Semicircle =302 ÷ 2 =151 m
Therefore:
Perimeter of the Two Semicircles at each end

Length of the Two rectangular sides =1408+1408 =2816m
Therefore, Length of Fencing Needed
