The dimensions that give the maximum area is 135 m by 135 m for a rectangular area with 540 m of fencing
What is an area?
An area is the amount of space occupied by a two dimensional shape or object.
Let w represent the width and l represent the length, hence:
540 = 2(l + w)
l = w - 270
The area (A) is:
A = length * width
A = w(w - 270) = w² - 270w
The domain of the function is (270, ∞), the range is (0, ∞).
The maximum area is at dA/dw = 0, hence:
2w - 270 = 0
w = 135 m, l = 270 - w = 135 m
The dimensions that give the maximum area is 135 m by 135 m
