Question

Q: 20 PQRS is a parallelogram. SL is perpendicular to PQ and QM is perpendicular to PS.
0 cu
8 cm
9 cm
L
If QM = 9 cm, SL = 6 cm and PS = 8 cm, what is the length of side PQ of the
parallelogram?
​

Answer 1

The are of parallelogram remains same in any case....

Here, area {taking ps base and corresponding altitude} is 72...

Now, taking pq base and sl altitude

area is 6 * pq = 72

So, PQ is 12...
