Question

the expression 4x gives the perimeter of a square with a side length of x units. what is the perimeter of a square with a side length of 5/7 units?

Explanation:

Step1: Recall perimeter formula for square

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

Step2: Substitute the given side - length

Here, the side - length $s=\frac{5}{7}$ units. So, $P = 4\times\frac{5}{7}$.

Step3: Calculate the result

$4\times\frac{5}{7}=\frac{20}{7}$ units.

Answer:

$\frac{20}{7}$ units
