Q. Each side of a square classroom is

5\,\text{meters}

long. The school wants to replace the carpet in the classroom with new carpet that costs

\$65.00

per square meter. How much will the new carpet cost?

\newline

\$\_\_\_

Calculate area of square: Calculate the area of the square classroom. $\newline$ Area = side length $\times$ side length = $5 \, \text{m} \times 5 \, \text{m} = 25 \, \text{m}^2$ .
Calculate total cost: Calculate the total cost of the new carpet. $\newline$ Total cost = area $\times$ cost per square meter = $25 \, \text{m}^2 \times \$65.00/\text{m}^2 = \$1625.00$ .
