In geometry, a Square is a flat figure or shape which has 4 equal sides and every angle is a right angle i.e. 90° and it shows equal sides. From this, it follows that the opposite sides are also parallel. It is also described as a rectangle which has 2 adjacent sides have equal length. The area of a square found out by the amount of space occupied within the square. Below mentioned is a formula to calculate the area of square. It is best known of the quadrilaterals in geometry. Square is simply a specific case of a regular polygon, in this case with 4 equal sides. All the facts and properties described for regular polygons apply to the square.

a is the length of the side of a square

### Solved Examples

**Question 1:**Find the area of the square of side 16 cm?

**Solution:**

Area of the square

= a

^{2}

= 16

^{2}cm

^{2}

= 256 cm

^{2}

**Question 2:**Find the length of the square whose area is 529 cm

^{2}?

**Solution:**

^{2}

**Side of the square = a = ?**

^{2}

⇒ 529 cm

^{2 }= a

^{2 }

⇒ a = √529

⇒ a = 23 cm
