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

side =1200cm= 12 m

so area of field = 12 * 12

= 144 m2

so cost of ploughing

= 144 * 75 = 10800rs

Answer 2

side=1200cm=12m
area of the square field=side^2=12×12=144m^2
Cost of ploughing 1 m^2=Rs75
cost of ploughing the whole field = 75×144=Rs10800
