A farmer creates a rectangular pen using part of the wall of a barn for one side of the pen and a total of 130 feet of fencing f
Nat2105 [25]

The equation that describes the which gives the area of the pen, A, as a function of x, the length of fence parallel to the barn is A = 130x - x²

<h3>How to find area of a rectangle?</h3>

The pen is rectangular. Therefore,

area of a rectangle = lw

where

  • l = length
  • w = width

Therefore,

perimeter = 2w + l

perimeter = 2w + x

130 = 2w + x

130 - x = 2w

w = 65 - 1/ 2 x

A = xw

A = x(65 - 1/ 2 x)

A = 65x - 1 / 2 x²

Therefore, the function that represents A, the area of the pen is as follows:

A = 130x - x²
