Point F is the middle of the segment EL, EF = 3 dm 12 cm. Find the length of the segment EL in meters.

Analysis of the task requirement shows that the answer, that is, the length of the segment EL, must be presented in meters. Based on this, we express the given length of the segment EF = 3 dm 12 cm in meters. Since 1 meter = 10 decimetres and 1 meter = 100 centimeters, we get EF = 3 dm 12 cm = (3: 10) m + (12: 100) m = 0.3 m + 0.12 m = 0.42 m …
If point F is the middle of the segment EL, then the lengths of the segments EF and FL are equal to each other, that is, EF = FL = 3 dm 12 cm = 0.42 m.
In order to find the length of the segment EL, you can add the lengths of the segments EF and FL. Then, we get: EL = EF + FL = 0.42 m + 0.42 m = (0 42 + 0.42) m = 0.84 m.
Answer: The length of the EL segment is 0.84 m.
