Question

PQRS is a parallelogram (Fig 11.23). OM is the height from Q
to SR and ON is the height from Q to PS. If SR = 12 cm and
QM = 7.6 cm. Find:​

Answer 1

HERE YOU GOOOO!! ;)

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= 91.2÷8 =11.4cm.
