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:

  1. the area of the parallelogram PQRS
  2. QN, if PS = 8 cm

Sum

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
