Maths
PORS is a parallelogram. QM is the height from Q to SR and QN is the height from Q to PS. IF SR = 12 cm and QM = 8 cm. Find: (a) the area of the parallelogram PQRS (b) QN, if PS = 3 cm​

Answer 1

Answer:

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

Area of parallelogram=base×height

=12×7.6=91.2cm2.

Area of parallelogram=base×height

⇒91.2=8×QN

⇒QN=891.2=11.4cm.
