Question

1. the area of a square is 49 m². how many meters long is each side of the square?

Explanation:

Step1: Recall area formula for square

The area formula of a square is $A = s^2$, where $A$ is the area and $s$ is the side - length.

Step2: Solve for side - length

Given $A = 49\ m^2$, we have $s^2=49$. Taking the square root of both sides, $s=\sqrt{49}$. Since the side - length of a square cannot be negative, $s = 7\ m$.

Answer:

7 m
