Answer:
1.) Circle
2.) It gives the maximum area among others
Explanation:
Given that the fencing material = 100 yard. That means circumference = 100
Circumference of a circle = 2πr
100 = 2πr
r = 50/ π
Area of a circle = πr^2
Area of a circle = π × (50/π)^2
= 2500/ π
= 795.77 squared yard
If the area of Pentagon is calculated, we will get 688 squared yard.
Also, if the area hexagon is calculated, we will get 716 square yard
