Question

the lenght and breadth of a rectangular field is 110m and 30m respectively.calculate the length of the longest rod which can measure the length and breadth of the field exactly.

Answer 1

So length -110
Breadth -30
Longest rod -2 * (L +B)
-2*140
280 cm

Answer 2

We will need a rod of 110 meters. To measure the length we can measure it by this rod and also we can measure a breadth which is smaller than the whole length.
