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:

(a) the area of the parallelogram PQRS

(b) QN, if PS = 8 cm

Answer 1

(a) Area of parallelogram = Base × Height = SR × QM

= 7.6 × 12 = 91.2 cm²

(b) Area of parallelogram = Base × Height = PS × QN = 91.2 cm²

QN × 8 = 91.2
