Question

Question 5 (b)

PQRS is a parallelogram 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 QN, if PS = 8 cm

Answer 1

Given: SR = 12 cm, QM = 7.6 cm, PS = 8 cm
Area of parallelogram = $base\times height$
$\Rightarrow$ $91.2=8\times QN$
$\Rightarrow$ $QN=\frac{91.2}{8}=11.4cm$
