Question

7. PORS is a parallelogram whose adjacent sides PQ =20 cm and QR =21 cm one of its diagonals
PR =18 cm, find
(i) the area of the parallelogram PQRS.
(ii) the distance between the longer sides.
(iii) the distance between the shorter sides.

Answer 1

Answer:

PQ=SR=20cm

RQ=PS=21cm

Now,

Area of llgm PQRS=2×Area of
