Question

c. area = 324 cm²
f. area = 6.25 m²
unctions

Explanation:

Step1: Recall area formula for square

The area formula for a square is $A = s^{2}$, where $A$ is the area and $s$ is the side - length. To find $s$, we use $s=\sqrt{A}$.

Step2: Solve for side - length of square c

Given $A = 324\ cm^{2}$, then $s=\sqrt{324}$. Since $18\times18 = 324$, $s = 18\ cm$.

Step3: Solve for side - length of square f

Given $A = 6.25\ m^{2}$, then $s=\sqrt{6.25}$. Since $2.5\times2.5=6.25$, $s = 2.5\ m$.

Answer:

For square c, the side - length $s = 18\ cm$. For square f, the side - length $s = 2.5\ m$.
