Answer:
1st piece = 15 inch
2nd piece = 15 inch
3rd piece = 30 inch
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
