Q. The expression

4x

gives the perimeter of a square with a side length of

x

units.

\newline

What is the perimeter of a square with a side length of

\frac{5}{7}

units?

\newline

\square

units

Perimeter of square calculation: The perimeter of a square is $4$ times the length of one side.
Multiply by side length: To find the perimeter, multiply $4$ by the side length, which is $\frac{5}{7}$ units.
Calculate perimeter: So, the perimeter $P$ is $P = 4 \times \frac{5}{7}$ .
Perform multiplication: Calculating the multiplication: $P = \frac{20}{7}$ .
Final perimeter: The perimeter of the square is $\frac{20}{7}$ units.
