Let the first piece of rope be x
The second piece of rope is then 4 + 2x
We know that together they were 82 cm. So we can write the equations as:
x=26, the length of the first piece of rope
4+2x=4+52=56, the length of the second piece of rope.
Ans.: The length of the two pieces of rope are 26cm and 56 cm.
