Question

multiple choice 1 point
the area of a square is 45. what is the length of the side of the square to the nearest tenth (one decimal place)?
20.25
6.7
22.5

Explanation:

Step1: Recall the area formula for a square

The area formula of a square is $A = s^{2}$, where $A$ is the area and $s$ is the side - length. Given $A = 45$, we have $s^{2}=45$.

Step2: Solve for the side - length

Taking the square root of both sides, $s=\sqrt{45}$. Calculate $\sqrt{45}\approx6.7082$.

Step3: Round to the nearest tenth

Rounding 6.7082 to the nearest tenth gives 6.7.

Answer:

B. 6.7
