Let the length of one of the shorter pieces be

. Then, we know that two of the pieces are that length, and the third piece is

. Since these are all pieces of a rope, all we need to do to figure out the lengths is add all those together, solve for

, and then plug that back in to the desired lengths:



Shorter pieces:

Longer piece:
