A square is a regular polygon with four sides. It has four
right angles and parallel sides.
Square Formula
Area of
Square = (a)²
Perimeter of
Square = 4(a)
Diagonal of
Square = (a)(sqrt(2))
where
a = side

Case 1:
Find the area, perimeter and diagonal of a square with the
given side 3.
Step 1:
Find the area. Area = (a)² = (3)² = 9.
Step 2:
Find the perimeter. Perimeter = 4(a) = 4 * 3 = 12.
Step 3:
Find the diagonal. Diagonal = (a)*(sqrt(2)) = 3 * 1.41 =
4.23.
The above example will clearly illustrates how to calculate the Area,
Perimeter and Diagonal of a Square manually.
