Answer: 20 Meters
Explanation:
First strand: 2x (twice the length of the shortest strand)
Second strand: 3x (three times the length of the shortest strand)
Third strand: x (the length of the shortest strand)
All the strands: 2x + 3x + x
All the strands: 6x
6x = 120 meters
(DIVIDE BOTH 6 AND 120 BY 6)
x=20
THE LENGTH OF THE SHORTEST STRAND IS 20 METERS
