Answer:
The distance around the bulletin board is 56 cm.
Step-by-step explanation:
Given : Heather is putting together a square bulletin board for her new room, and the area of the bulletin board is 196 cm.
To find : What is the total distance around the bulletin board?
Solution :
We have given the area of the square bulletin board A=196 cm.
The side of the square is given by,
[tex]A=s^2[/tex]
[tex]196=s^2[/tex]
[tex]s=\sqrt{196}[/tex]
[tex]s=14[/tex]
Now, The distance around the bulletin board is the perimeter of the board.
Perimeter of the square is [tex]P=4\times s[/tex]
[tex]P=4\times 14[/tex]
[tex]P=56[/tex]
Therefore, The distance around the bulletin board is 56 cm.
The total distance around the bulletin board is 56cm
A square is a two-dimensional shape with four equal sides.
Area of a square = length²
196 = length²
length = √196
length = 14 cm
The total distance round the board is the perimeter of the board
Perimeter of a square = 4 x length
4 x 14 = 56 cm
