The area of the square is the length multiplied by the width but as these are of equal length (call this d) then the area is given by the formula d x d = d²
If the area is 61 sq cm (written 61 cm²) then :
d² = 61, so d = √61 = 7.81 (to 2 decimal places)
The length of each side is therefore 7.81 cm
The total length of all four sides is thus 4 x 7.81 = 31.24 cm

Square root the area. The length and width of a square are always the same and length times width is the area so this is how you get the area.
The size or length of a square is related to its area as the area of a rectangle s the product of the length times the width. As a square is a special type of rectangle, where the length is equal ti the width, the area of a square is the length times the length or length^2, also spoken as "length squared".
A square with a side length of 4cm has an area of 16cm2
For a rectangle or square, Area = Length * Width So Length = Area / Width.
The area of square is : 25.0
