Question:
PQRS is a parallelogram. QM is the height from Q to SR and QN is height from Q to PS.If SR=12cm and QM=7.6 cm, find the area of parallelogram PQRSand also find QN if PS=8cm
Answer:
Given, base = 12 cm, Height = 7.6 cm
Now, the area of the parallelogram PQRS = base * height
= 12 * 7.6
= 91.6 cm2
Again given, base PS = 8 cm
Now, area of parallelogram = base * height
=> 91.6 = 8 * QN
=> QN = 91.6/8
=> QN = 11.4 cm
