bulletin board is 196 cm.? What is the total distance around the bulletin board?

Respuesta :

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
