Solution:The we have ΔAPQ, quadrilateral PQRS are on the some PQ and between the some parallels PQ॥ SR.
⇒ ΔAPQ =½ PQRS
⇒ PQRS - ΔAAPQ = ½ pQRS
⇒ ½ PQRS = ΔASP +ΔARQ
⇒ The farmer may saw groundnuts on ΔAPQ region
The farmer may sow pulses on ΔASP region
The farmer may sow paddy on ΔARQ region
Hence, option 1 is correct.
