Question

1. heather is putting together a square bulletin board for her new room, and the area of the bulletin board is 196 cm². what is the total distance around the bulletin board?

Explanation:

Step1: Find side - length of square

The area formula of a square is $A = s^{2}$, where $A$ is area and $s$ is side - length. Given $A = 196\ cm^{2}$, then $s=\sqrt{A}=\sqrt{196}=14\ cm$.

Step2: Calculate perimeter of square

The perimeter formula of a square is $P = 4s$. Substitute $s = 14\ cm$ into the formula, we get $P=4\times14 = 56\ cm$.

Answer:

$56\ cm$
