respectively, then find the length of the third piece.

Answers
Answer:
"Let S = shortest piece, M = middle piece, and L = longest piece. The stem says that S + M + L = 27 meters.
(1) INSUFFICIENT. The statement says L = 2S. However, the statement says nothing about the length of M. As a result, more than one solution is possible. For example, if S = 6, then L = 12 and M = 9. Or, if S = 5.5, then L = 11 and M = 10.5.
(2) SUFFICIENT. This statement says S + M = 15. If you substitute this equation into the original equation provided in the stem, you have:
S + M + L = 27 (original equation)
15 + L = 27 (substitute 15 for "S + M")
L = 12 (subtract 15 from both sides)"
Step-by-step explanation:
The sum of the length of the two shorter pieces is 15 meters
Answer:
Given, Total length =12 m
Length of a one piece =4.29 m
Length of other piece = total length - length of one piece
=12−4.29
=7.71 m
