The cost of ploughing a square farm is the same as ploughing another farm that is rectangular in shape.the rate of ploughing is the same in both the cases. The side of the square farm is 20m and the length of the rectangular farm is 40m. Find the breath of the farm.

Answer 1

25

Answer 2

If the time is the same, and the rate is the same, the area of the two fields must be equal
so (40)(w) = 20^2
w = 400/40 = 10

A farm which is 10 m wide ?
mmmhhh....
