Question

If a side of a square field is 1200 CM if rate for ploughing the whole field is 75 per metre find the rate of ploughing the whole field

Answer 1

1200 cm is 12 m.

Rate is 75/m

Therefore total rate is 75×12=900.

Answer 2

length of field=1200 cm=1200/100 m=12m

rate=75/m

cost=lenght * rate

     =12*75

     Rs 900
