Question

The area of a square is $36$ sq. cm. How long is each side?

• A. $4$ cm
• B. $6$ cm
• C. $8$ cm
• D. $3$ cm

Answer 1

Answer: (B)

Area of square $={\text{side}}^2$

Therefore, $36={\text{side}}^2$

$\Rightarrow \text{side}=6$ cm
The sides of a square are all the same length, so each side must be $6$ centimeters long.
