Answer:
Step-by-step explanation:
Given the length of the pieces; 45 cm, 75 cm, and 81 cm
To find the length of the rope we have to find the L.C.M. of 45, 75 and 81.
L.C.M. = 3×3×3×3×5×5.
= 2025 cm
So, the least length of the rope should be 2025 cm which can be cut into the whole number of pieces of length 45 cm, 75 cm, and 81 cm.
