Question

Xin Used 20 yards of fencing to build the walls of a square a chicken coop. Used 20 yards of fencing to build the walls of a square chicken coop Which equation and solution represent X , The length , in yards , Of each wall oF the square coop

Answer 1

5

Explanation:

4x=20

so divide 20 by 4 and you get 5

Answer 2

Equation:
`20=4x` or
`x=(20)/(4)`

Solution:
`x=5`

Explanation:

The formula that is used to calculate the perimeter of a square is:

`P=4s`

Where "s" is the side lenght the square.

Knowing that Xin used 20 yards of fencing to build the walls of a square chicken coop (in which the lenght in yards of each wall is represented with "x"), you can identify that:

`P=20\\\\s=x`

Then, you can susbtitute values into the formula
`P=4s`:

`20=4x`

Finally, you must solve for "x" in order to find its value.

This is:

`(20)/(4)=x\\\\x=5`
