# PQRS is a parallelogram (Fig 11.23). 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:

(a) the area of the parallelogram PQRS

(b) QN, if PS = 8 cm

**Solution:**

(a) SR = 12 cm and QM = 7.6 cm.

Area of parallelogram PQRS = Base × Height

= SR × QM

= 12 cm × 7.6 cm

= 91.2 cm^{2}

(b) Base = PS = 8 cm

Area of the parallelogram = 91.2 cm^{2} [calculated in part (a)]

Area of parallelogram PQRS = Base × Height

91.2 cm^{2 }= 8 cm × QN

QN = 91.2 cm^{2 }/ 8 cm

QN = 11.4 cm
