Area of Square

What is Area?

Area is the size of a surface!

It is the amount of space inside the boundary of a flat object (such as a square or circle). Area is a measurement of the space inside the boundaries (edges) of a flat (2-D (two dimensional)) object. It can also be simplified as “surface” area, a measurement of an object’s surface.

The area of a shape is a number that tells how many square units are needed to cover the shape. Area can be measured in different units, such as square feet, square meters, or square inches.


A Square is a flat shape with 4 (four) equal sides and every angle is a right angle (90° (ninety degrees)).

A square also fits the definition of a rectangle (all angles are 90°(ninety degrees)), and a rhombus (all sides are equal length).


  • Area of a Square

The area of a square can be obtained by multiplying the lengths of the two sides. Since the lengths of the sides are the same in a square, we just square the length of the side to get the area.
