The length and breadth of a room are 825 cm and 675 cm respectively. What is the
length of the longest tape that can measure the two dimensions exactly?​

Answer 1

Answer:

length of room = 825 and

breadth of room = 675

length of longest tape

then we find HCF

HCF of 825 = 3x5x5x11

HCF of 675 =3x3x3x5x5

common in both 3x5x5

= 75 cm
