Square has an area of 2 116²cm. What is the perimeter in metres?

To find the perimeter of the square, we first need to find the length of one side of the square.

The formula for the area of a square is:

Area = side length * side length

Given that the area of the square is 2116 cm², we can set up the equation:

2116 = side length * side length

Taking the square root of both sides, we get:

√2116 = side length
46 = side length

Now that we know the side length is 46 cm, we can find the perimeter of the square by multiplying the side length by 4 (since a square has four equal sides):

Perimeter = 46 cm * 4 = 184 cm

To convert the perimeter from centimeters to meters, we divide by 100:

184 cm / 100 = 1.84 m

Therefore, the perimeter of the square is 1.84 meters.

The answer is: 252m

Chain-of-thought:

Since the area of a square is the side length squared, the side length is 46cm.

Since 1m = 100cm, the side length in metres is 46cm/100cm/m = 0.46m.

The perimeter of a square is 4 - side length, so the perimeter in metres is 4 - 0.46m = 1.84m.
