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

Answer:

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:

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