Question

the length and breadth of a room are 3 m and 4 metres. what is the length of the longest metallic rod that can be placed on the floor?

Answer 1

Hi ,

Dimensions of room are ,

Length = l = 3 m ,

Breadth = b = 4 m

Length of the Longest rod placed in

the room = length of the diagonal of the floor

= √ l² + b²

= √ 3² + 4²

= √ 9 + 16

= √ 25

= 5

I hope this helps you.

Answer 2

Assuming that the room is rectangular in shape, the length of the longest rod that can be placed on the floor would be equal to the length of the hypotenuse formed by the triangle with the sides 3m and 4m long as its sides

Let the hypotenuse be X
X^2=3^2+4^2
X^2=25
Or X = 5
Hence the length of the longest rod would be 5m
