Question

area of parallelogram PQRS is 96cm^2 If areac∆ PMS=20cm^2 find the area of ∆ RMQ​

Answer 1

Step-by-step explanation:

I think the question has diagram. and m is the intersecting point of both the diagonal. if so I ll do the ans for you.

in ∆pqs, pm is the median (diagonal of //gram bisect each other)

therefore ar. of the ∆ pms= ar. of the ∆ pmq

ar. of the ∆pms= 1/2 of the ar. of the ∆pqs----------1

similarly in ∆ qrs, rm is the median

therefore ar. of the ∆qmr = 1/2 of the ar. of ∆qrs--------- 2

from 1and 2 we have

ar. of the ∆pms= ar. of the ∆ rmq

therefore ar. of the ∆ rmq= 20 cm^2

(note:- the diagonal bisects the //gram into two equal ∆. so ar. of ∆ pqs= ar. of ∆rqs
