hey friend!!!

your answer is "75cm"

Explaination

Length, breadth and height of a room are 8 m 25 cm, 6 m 75 cm and 4 m 50 cm, respectively.

Length = 825 cm

Breadth = 675 cm

Height = 450 cm

HCF of 825, 675, 450

825 5 x 5 x 3 x 11 675 5 x 5 x 3x3x3

450 = 2 x 3 x 3x5x5

HCF = 5 x 5 x 3 = 75cm_

_answer

Therefore, the length of the longest rod which can measure the three dimensions of the room exactly is 75 cm
