the formula for the area of a square is the length of one side squared.
area = side2
or another way is to say that
side = square root of area
since you know area is 169 then side = square root of 169 = 13
multiply the length of the side by another length of the side
You multiply the length of a side by the square root of 2.If you only have the area, square root it to find the length of a side.
To find the length of one side of a square when given the area, you need to take the square root of the area. In this case, the area of the square is 225. Taking the square root of 225 gives you 15. Therefore, the length of one side of the square is 15 units.
Area = length * width. A square has four equal length sides, so the length of a side = √24, or approximately 4.90 ft.
The area of a square is one side multiplied by an adjacent side. In a square all sides are the same length. Then the square root of the area must be the length of any side. If you know the area you can look up the square root in tables found in many older math books, or simply find the square on your calculator.
