Equation: 20=4x or $x=\frac{20}{4}$

Solution: x=5

Step-by-step 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:

$\frac{20}{4}=x\\\\x=5$
