To find the length of fencing the farmer needs to buy, we first need to determine the length of one side of the square field.
As the area of the square field is given by the formula A = side^2, we can rearrange the formula to solve for the side length:
side^2 = A
side^2 = 3600m^2
Taking the square root of both sides, we have:
side = √(3600m^2)
side = 60m
Since a square has four equal sides, the length of fencing the farmer needs to buy is 4 times the length of one side:
fencing length = 4 x 60m
fencing length = 240m
Therefore, the farmer needs to buy 240m of fencing.
A farmer is buying fencing to surround a square field of area 3600m^2.
