given ,
heights=as(40cm)and af(60cm)
area of parallelogram=1200cm²
=>base x height =1200cm²
for height ae,
=>b x ae=1200cm²
=>b x 40cm=1200cm²
=>b=1200cm²/40cm
=>b=30cm
for height af
=>b x af=1200cm²
=>b x 60cm= 1200cm²
=> b = 1200cm²/60cm
=>b=20cm
therefore the length of the parallelogram are : 30cm and 20 cm
hope it's the required answer....
