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)).
- 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.
Find the area of a square flower-bed of side 15 m (fifteen meters).
- Diagonals of a Square
A square has two diagonals, they are equal in length and intersect in the middle.
