A Square is a 4-sided regular polygon with all sides equal and all internal angles 90 degree. It is a four sided polygon characterized by right angles and sides of equal length.
Area of square: [(side)²]
Perimeter of square: [4(side)]
Diagonal of square: [(side) (sqrt(2))]

Calculate the Area, Perimeter and Diagonal of a Square whose length is 10 cm.
Step1: Area of square: [(side)²]
Area of square = 102 = 100
Step 2: Perimeter of square: [4(side)]
Perimeter of square=4*10 = 40
Step 3: Diagonal of square: [(side) (sqrt(2)) ]
Diagonal of square=10 * sqrt(2) =10*1.41 = 14.1
