Answer
∆CPD and ||gm ABCD are on the same base CD and between the same parallel lines AB and CD.
Area of ∆CPD = Area of ||gm ABCD ……(1)
∆AQD and ||gm ABCD are on the same base AD and between the same parallel lines AD and BC.
Area of ∆AQD = Area of ||gm ABCD ……(2)
From equations (1) and (2), we get :
Area of ∆CPD = Area of ∆AQD.
Hence, proved that area of ∆CPD = area of ∆AQD.
