What is the area of a square whose sides are 9?
A square with a side length of 9 units has an area of 81 square units.
How do we find the width of a square if you only have the area?
We know that every side of a square in the same length, and that the area is equal to the width times the height. Because this is a square, the width and height are equal, so area is equal to the length of one of the sides times itself, or the length of one of the sides squared. So, in order to find the length of one of the sides, you take the square root of the area. The length of the side is equal to both the width and the height. For example, if you have a square with an area of 9, take the square root of 9, which is 3. So the width of that square is 3.
What is the perimetre of a square if it has an area of 81 cm2?
Oh, what a happy little question! To find the perimeter of a square when you know its area, you first need to find the length of one side by taking the square root of the area. In this case, the side length would be 9 cm, so the perimeter would be 36 cm since all sides of a square are equal. Just remember, there are no mistakes in math, only happy little accidents!
Length of a diagonal square with area of 81?
The length of a square with an area of 81 would be 9.
What is the square of 9?
The square of 9 is calculated by multiplying 9 by itself, which equals 81. In mathematical terms, this can be written as 9^2 = 81. The square of a number represents the area of a square with sides of that length.
