Answer 1

Answer:

50m

Step-by-step explanation:

The distance between two opposite corners of the hall

$= \sqrt{ {length}^{2} + {breadth}^{2} } \\ = \sqrt{ {(40m)}^{2} + {(30m) }^{2} } \: \: \: \: \: \\ = \sqrt{1600 {m}^{2} + 900 {m}^{2} } \: \: \: \: \: \: \\ = \sqrt{2500 {m}^{2} } \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ = 50m \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$
