Can somebody please explain me the following point: 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(P)+ar(Q),where ar(X) denotes the area of figure X Thank you Share with your friends Share 1 Varun.Rawat answered this Consider the following examples:1. Consider a ∥gm ABCD in which diagonal AC is joined. ar∥gm ABCD = ar∆ABC + ar∆ADCHere the triangular regions ABC and ADC are non overlapping. 2.Consider a ∆ABC, in which AD is median to BC. ar∆ABC = ar∆ADC + ar∆ADBHere ∆ADC and ∆ADB are non overlapping regions. 0 View Full Answer
