calculate the largest area possible that can be made by a 15 meter long wire that will be bent to form a closed plane area. No figure given

Answer 1

the largest area of course is contained within a circle.
So if the perimeter is 15 m
then 2πr = 15
r = 15/(2π)

area = π(15/(2π))^2
= 225/(4π) m^2 or appr 17.9 m^2
