Q. Each side of a square newspaper ad is

20\,\text{centimeters}

long. What is the newspaper ad's perimeter?

\newline

\_\_\_\_\_\_

centimeters

Identify Perimeter Calculation: To find the perimeter of a square, we need to add up the lengths of all four sides. Since all sides of a square are equal, we can simply multiply the length of one side by $4$ . $\newline$ Calculation: $20 \, \text{cm}$ (length of one side) $\times 4$ (number of sides) $= 80 \, \text{cm}$
