Square side calculator

In geometry, a side can be defined as a line connecting two vertices of a figure or two-dimensional figure. Our online calculator will help you find the side, edge of more than 11 shapes.

Square — is a rectangle with equal sides. One can also give another definition of a square: a square is a rhombus in which all angles are straight. It turns out that the square has all the properties of a parallelogram, rectangle, and rhombus.

If you need to find the length of the sides of a square, our free online square side calculator can help. Simply input the length of diagonal, and our calculator will calculate the length of the four sides of the square.

Square Side Formula

There are several formulas that you can use to calculate the length of a side of a square. If we have the diagonal of the square, then based on the Pythagorean theorem in the right triangle that forms the diagonal, the side will be equal to the diagonal divided by the root of two as in above formula. Also the side can be found by perimeter or by the area of the square.

a = \dfrac{d}{\sqrt{2}}

Example Problems

Here are some examples of how to use the formulas to find the length of the sides of a square.

Example 1

Find the perimeter and area of a square where the length of diagonal is 5 units.

a = \dfrac{5}{\sqrt{2}} = 3.53

Therefore, the side of the square is 3.53 units.

Example 2

Find the length of one side of a square where the diagonal is 24 units.

a = \dfrac{24}{\sqrt{2}} = 16.97

Therefore, the length of one side of the square is 16.97 units.
