Question

9. Find the length of the largest pole that can be placed in a hall 10 m long, 10 m wide and
5 m high.
Hint. Length of the diagonal of the room = √1 sq + b sq +h sq
​

Answer 1

Answer:

length of the diagonal of the room

=√(length^2+breadth^2+height^2 ) m

=√(10^2+10^2+5^2) m

=√(100+100+25) m

=√225 m

=15 m

so the length of the largest pole that can be placed in a hall is 15 m
