Question

0. PQRS 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=6 cm ,find:
a) The area of parallelogram PQRS
b) The length of QN, if PS=8 cm.

Answer 1

Answer:

Step-by-step explanation:

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= 9.12/8 = 11.4cm.
