12 cm
if one length is 9cm, the other length must be 6cm to make an area of 54cm. hence the perimeter is 9+9+6+6 = 30cm
For a square Area = Side2 thus Side = √Area = √81 = 9cmFor a square, Perimeter = 4 x Side = 4 x 9 = 36cm
If the area of a square is 81, then the length of a side is 9. Add up the length of all four sides to get the perimeter: 9 + 9 + 9 + 9
Area = 9 sq inches Length of side = sqrt(9) = 3 inches Perimeter = 4*Length of side = 4*3 = 12 inches
It is: 4*9 = 36 inches
The area is 9 cm212 / 4 = 33 * 3 = 9
The sidelength of a square is the square root of its area, and its perimeter is four time this. 4 x sqrt(9 cm2) = 12 centimetres.
If it's a square, then each side should be 3 cm, meaning perimeter is 12cm
4 root 9 ie 12 cm
if one length is 9cm, the other length must be 6cm to make an area of 54cm. hence the perimeter is 9+9+6+6 = 30cm
For a square Area = Side2 thus Side = √Area = √81 = 9cmFor a square, Perimeter = 4 x Side = 4 x 9 = 36cm
The idea is to first calculate the length of one side. Then you can multiply that by 4 to get the perimeter.
9 x 9 = 81cm2Therefore, each of the 4 sides of the square measures 9cm.The perimeter is: 9 x 4 = 36cm
That will depend on its dimensions of which none have been given but if they are 2 by 9 then its perimeter is 22 cm or if they are 3 by 6 then its perimeter is 18 cm
The area of a square with a perimeter of 12 feet is: 9 square feet.
The area is 9 square feet.
Area = 9 cm * 4 cm = 36 square cm
