Rectangle of length 72 feet and breadth 36 feet has largest area
What is maxima and minima?
Maxima of function f(x) is the maximum value of the function and minima of function f(x) is the minimum value of the function.
Here,
Let the length be x feet and breadth be y feet
The farmer has 144 feet of fencing
Three of the sides will require fencing and the fourth wall already exists.
So,
x + y + y =1 44
x + 2y = 144
Area of rectangle(A) = xy
= (144 - 2y)y
=
=
For largest area,
Hence area is maximum
For largest area, y = 36 feet
feet
So length of rectangle is 72 feet, breadth of rectangle is 36 feet
