**Jalita**, Sunday, September 15, 2013 at 12:11pmIf piece 2 is twice piece 1, then

x = piece 1

3x = piece 3 (3 times piece 1)

2x = piece 2 (twice piece 1)

x + 3x + 2x = 42

6x = 42

x = 7

Piece 1 - 7

Piece 2 - 14

Piece 3 - 21

x = piece 1

3x = piece 3 (3 times piece 1)

2(3x) = piece 2 (twice piece 3)

x + 3x + 2(3x) = 42

10x = 42

x = 4.2

Piece 1 - 4.2

Piece 2 - 12.6

Piece 3 - 25.2

**Anonymous**, Sunday, September 15, 2013 at 2:18pmI'm confused. Shouldn't pc 2 be the largest since it says that pc2 is twice as long as pc 1&3, and pc 3/three times as long as pc1
