Answer:
One piece is 26 inches long while the other is 52 inches long.
We let:
x = one piece of the thread
2x = the other piece of the thread
Since the thread is 78 inches long,
2x + x = 78
Solve for x:
Since one piece of the thread is 26 inches long, the other piece would be:
The other piece would be 52 inches long.
Step 1: let x be the length of the two shorter sides and x+5 be the length of the longer side
Step 2: perimeter= the lengths of the three sides added together
Step 3: solve for x
Step 4: the longer side = x+5
So, the answer is 13.
