Given:
Width of rectangular backyard =
feet
Length of rectangular backyard =
feet
To find:
The perimeter of yard.
Solution:
Formula or perimeter of a rectangle is
![Perimeter=2(length +width)](https://tex.z-dn.net/?f=Perimeter%3D2%28length%20%2Bwidth%29)
Using this formula, the perimeter of the rectangular backyard is
![Perimeter=2(4xy+5x^3y^2+3x^2)](https://tex.z-dn.net/?f=Perimeter%3D2%284xy%2B5x%5E3y%5E2%2B3x%5E2%29)
![Perimeter=8xy+10x^3y^2+6x^2](https://tex.z-dn.net/?f=Perimeter%3D8xy%2B10x%5E3y%5E2%2B6x%5E2)
Therefore, the perimeter of the rectangular backyard is
feet. So,
feet fencing is needed.
