Here are some basic maths formulas for a calculation of area and volume of a Square and Rectangle

Area of the Square : a x a – Where a is the side of the square

Perimeter of the Square: 4 a

Length of diagonal : Square root of side of the Square

For Rectangle : Perimeter rectangle: 2 ( c + d)

Area of Rectangle : c x d

Diagonal = Add the square of c and square of d
