What is the length of the added metal bar?
a
Approximately 5.4 m
b
Exactly 29 m
c
Approximately 14.5 m
d
Exactly 5 m
c
Approximately 14.5 m
The length of the added metal bar is approximately 14.5 m (option c).
To determine the length of the added metal bar, we need to carefully analyze the given options and find the most suitable answer.
a) Approximately 5.4 m: This option suggests an approximate length of 5.4 meters for the added metal bar. However, this does not match any of the other options precisely, so we can eliminate this choice.
b) Exactly 29 m: This option states that the length of the added metal bar is exactly 29 meters. It is important to note that this directly conflicts with option d, which states the exact length as 5 meters. Therefore, we can eliminate this choice as well.
c) Approximately 14.5 m: This option suggests an approximate length of 14.5 meters for the added metal bar. As there are no other options close to this length, we cannot determine whether it is the correct answer or not. Thus, we need to consider the final option.
d) Exactly 5 m: This option states that the length of the added metal bar is exactly 5 meters. However, as mentioned earlier, this contradicts option b, which claims the length as exactly 29 meters. To resolve this inconsistency, one of these options must be incorrect.
In conclusion, based on the given information, we cannot definitively determine the length of the added metal bar. It is possible that there is a mistake in the options provided, or additional information is required to accurately find the length.
