Question
PQRS is a parallelogram (see the given figure). 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:
- the area of the parallelogram PQRS
- QN, if PS = 8 cm

Solution
a. Area of parallelogram = Base × Height
= SR × QM
= 7.6 × 12
= 91.2 cm2
b. Area of parallelogram = Base × Height
91.2 cm2 = PS × QN
QN × 8 = 91.2
QN = `91.2/8`
QN = 11.4 cm
