Question

the graph below shows the relationship between the perimeter of a square and the length of a side of the square. which proportion could be used to find x, the length of the side of a square with a perimeter of 70 inches? perimeter (in inches) length of a side (in inches)

Explanation:

Step1: Recall perimeter formula for square

The perimeter $P$ of a square is given by $P = 4s$, where $s$ is the side - length of the square.

Step2: Set up the proportion

We know $P = 70$ inches. So, $\frac{P}{s}=\frac{4}{1}$. Substituting $P = 70$, we get $\frac{70}{s}=\frac{4}{1}$.

Answer:

$\frac{70}{s}=\frac{4}{1}$
