To calculate Dimensional Formula of Area, we need to know its formula

Area = Length x Breadth
Area = L x L
Area = L²

So Dimensional Formula = [M⁰ L² T⁰]
SI unit of Area is m²

Dimensional Formula is a standardized method to express the Physical quantities in terms of basic quantities as chosen in the SI system of measurement. These are denoted with symbols in square brackets []

The seven standards as per SI are
1) Mass
2) Length
3) Time
4) Electric Current [A]
5) Thermodynamical Temperature [K]
6) Luminous Intensity [Cd]
7) Amount of Substance [mol]

Following are the most commonly and widely used algebra equations.

1) (a+b)²=a²+b²+2ab
2) (a-b)²=a²+b²-2ab
3) (a+b+c)²=a²+b²+c²+2ab+2bc+2ca
4) (a+b)(a-b)= a²-b²
5) (a+b)³= a³+b³+3ab(a+b)
6) (a-b)³= a³-b³-3ab(a-b)
7) (a+b)²-(a-b)²=4ab
8 ) (a+b)²+(a-b)²=2(a²+b²)
