Lets Start Preparing
All Important formula’s of 2-Dimensionals Figures for SSC Exam:-
We need to find out Area & Perimeter
Rectangle:-
Area:- a*b
Perimeter:- 2(a+b)
Square:-
Area:- a*a
Perimeter:- 4a
Right Angle Triangle:-
(Base)^2 + (altitude)^2 = (Hypotenuse)^2
Perimeter:- b+h+a
Area:- 1/2ab
For all triangles:-
Perimeter:- a+b+c (Where a,b,c are sides of triangle)
s=1/2(a+b+c) = (Semi Perimeter)
Area:- √s(s-a)(s-b)(s-c) – Hero’s Formula
