Ineed on number 2 , would really appreciate the !

1st piece = 15 inch

2nd piece = 15 inch

3rd piece = 30 inch

Step-by-step explanation:

2.

Let length of first piece be x

since 2nd piece is same, so 2nd piece's length is also x

third piece is TWICE, so its length is 2x

Total length of all the 3 pieces is 60, so we setup an equation and solve for x:

x + x + 2x = 60

4x = 60

x = 60/4 = 15

Hence, first piece is 15, second piece is 15, third piece is 2(15) = 30
