Lengths to be measured = 8 m 75 cm, 1.75 m, 12 m 20 cm
Concept:
The concept of finding the greatest common divisor (GCD) is used here. The GCD of the given lengths will be the greatest length that can measure all of them exactly.
Calculation:
Convert all measurements to the same unit (cm): 875 cm, 175 cm, and 1220 cm.
⇒ Find GCD(875, 175, 1220) = 5 cm.
Therefore, the greatest possible length which can be used to measure exactly the lengths 8 m 75 cm, 1.75 m and 12 m 20 cm is 5 cm.
