The length and breadth of a rectangular plot are 540 m and 380 m find the length of the longest rod which can measure the dimension of the plot exactly

Answer 1

Answer:

the longest rod can be put as a diagonal(d)

$d {}^{2} = l {}^{2} + b {}^{2} \\ = 540 { }^{2} + 380 {}^{2} \\ = 291600 + 144400 \\ = \sqrt{436000 } \\ = 660.3m \: \: answer$
