Class 9 Maths Areas Parallelograms Triangles Area sum Property

Area sum Property:

Sometime we need to find the area of complex figures which is made up of simple figures. If a planar region formed by a figure T is made up of two non-overlapping planar regions formed by figures P and Q, then ar(T) = ar(P) + ar(Q)

 

In the figure above, Area of cartoon = ar(A) + ar(B) + ar(C) + ar(D) + ar(E) + ar(F)
