If I'm correct, the area of a square, or any rectangle (a square is also a rectangle) = side x side.
Since all sides of a square are = to each other, the area of a square = length of one side, squared.
So you'd need the square root of 81 to find the length of one side = 9. Perimeter of an object is the sum of it's sides. Square has 4 sides, so 9+9+9+9 = 36

What is the width of a square with an area of 81 cm2?
Use your calculator to calculate the square root of 81. Or use trial-and-error, to see which number, when multiplied by itself, gives you 81. (Hint: In this case, it is an integer.)
What is 9cm square?
This is one of those areas where there is ambiguity.A 9 cm square is a square whose sides are 9 cm and which therefore has an area of 81 cm2.But 9 cm2 represents an area of 9 square centimetres. The shape of this area is unspecified.When written in the above form, the ambiguity is less obvious but in spoken form it is.
What is the surface area of a cube with edges measuring 9 centimeters?
A cube has six faces. Therefore, its surface area is 6 times a face's area.The area of a square whose edges measure 9 cm is 81 cm2.Therefore, the surface area of a cube whose edges measure 9 cm is 6*81 = 486 cm2.
