PQRS IS A TRAPEZIUM WITH PQ||SR. SIDE SR IS PRODUCED TO X SUCH THAT RX=PQ. PROVE THAT AR(PSQ)=AR(QRX)
Answer :
We have a trapezium PQRS , As PQ | | SR , and We extend R as RX = PQ , SO
PQ | | XS , As given PQ | | SR and we get XS after extend SR to " X " .
And we know two parallel line always have same distance between each other , So we take that distance = h , And our diagram , As :
We know Area of triangle = , So
Area of PSQ = ---------- ( 1 )
And
Area of QRX = , Given PQ = RX , SO we get
Area of QRX = ---------- ( 2 )
From equation 1 and 2 , we get
Area of PSQ =Area of QRX ( Hence proved )
