Step-by-step explanation:
Let's say x is the length of the first piece.
The second piece is 2x.
The third piece is 2x.
So the total length is:
x + 2x + 2x = 279
5x = 279
x = 55.8
That means 2x = 111.6.
So the first piece is 55.8 feet, the second piece is 111.6 feet, and the third piece is also 111.6 feet.
