Answer 1

27.

Join AC and QP, also it is given that AQ || CP

∴ △ACQ and △APQ are on the same base AQ and lie between the same parallels AQ || CP.

∴ ar(△ACQ) = ar(△APQ)

or ar(△ABC) + ar(△ABQ)

= ar(△BPQ) + ar(△ABQ)

or ar(△ABC) = ar(△BPQ)

or 1/2 ar(||gm ABCD) = 1/2 ar(||gm PBQR)

or ar(||gm ABCD) = ar(||gm PBQR).
