Question

PQRS is a parallelogram. QM is the
perpendicular from Q to SR and QN
is the perpendicular from Q to PS.
If SR = 12 cm and QM= 6 cm, find
the area of a parallelogram PQRS.
Also find QN if PS = 4 cm.

Answer 1

SR=12cm, QM=6cm, PS=4cm.

Area of parallelogram=base×height

12×6=72 cm^2

Area of parallelogram=base×height

72=4×QN

QN=72/4=18 cm
