Question

a room is 8 metre long a rod of length 10 metre has been hardly fitted into the room on its floor from its one corner to the opposite corner what is the breadth of the room

Answer 1

if you notice it would form a right angled triangle
even rod is acting as a hypotenuse



8^2+b^2=10^2

b=6m

Answer 2

Breadth is 6m
Solution:
Using pythogorous theorem
Hyp = 10m (longest side)
One of the side is 8m
Then the other side must be equal to 6m
