Question

PQRS is a parallelogram (Fig 11.23). QM is the height from Q
to SR and QN is the height from Q to PS. If SR = 12 cm and
QM = 7.6 cm. Find:
(a) the area of the parallegram PQRS (b) QN, if PS = 8 cm

Answer 1

Given: SR=12cm, QM=7.6cm, PS=8cm.

Area of parallelogram=base×height

=12×7.6=91.2cm

2

.

Area of parallelogram=base×height

⇒91.2=8×QN

⇒QN=

8

91.2

=11.4cm.
