Answer»

a) Given, Base = 12 cm, Height = 7.6 cm

Area of the parallelogram PQRS = Base××Height=12cm×7.6cm=91.2=12cm×7.6cm=91.2sq cm

(b) Given; Base PS = 8cm, Area of the parallelogram(as calculated in the above question) = 91.2 cm2, Height QN= ?

Area = Base××Height⇒91.2cm2=8cm×QN⇒91.2cm2=8cm×QNOr,QN=91.28=11.4QN=91.28=11.4cm
