Answer:
20 m
Step-by-step explanation:
The width is half the length, and the perimeter is the sum of the lengths of all sides. We can write the equation of the perimeter as ...
... 60 m = L + L/2 + L + L/2
... 60 m = 3L . . . . . collect terms
... 20 m = L . . . . . . divide by 3
The equation of a circle with a center of (h,k) with a radius of "r" is
looking at the given equation,
5x^2 +5y^2=20
divide 5 to both sides to get
x^2+y^2 =4
now compare that to the equatio of a circle shown above
