# What is the approximate side length of the square?

3.0 units, 3.5 units, 4.2 units, 4.9 units

**Solution:**

The properties of diagonals of square are

1. The diagonals bisect each other and meet at 90 degree.

2. The diagonals bisect its angles.

3. The diagonals are equal.

Let us consider the length of side as x

Using the Pythagoras theorem

3^{2} + 3^{2} = x^{2}

By further calculation

x^{2} = 9 + 9

x^{2} = 18

So we get

x = √18

x = 4.24 ≈ 4.2

Therefore, the approximate side length of the square is 4.2 units.

## What is the approximate side length of the square?
