Question

PORS is a parallelogram (Fig 11.23). QM is the height from Q
TSR and ON is the height from Q to PS. If SR = 12 cm and
ONT=76em. Find
al the area of the parallegram PQRS (b) QN, if PS = 8 cm​

Answer 1

QM as height = 7.6 c.m

SR as base = 12 c.m

We know that,

(i) Area of parallelogram = Base × Height

SR×QM

=12×7.6

Area of parallelogram = 91.2 c.m^2

(ii) find QN, if PS = 8 c.m.

According to the given figure.

Base PS = 8 c.m

Height QN = ?

We know that,

Area of parallelogram = PS×QN

91.2=8×QN

QN= 91.2/8

QN=11.4c.m

Hence, this is the answer.
