Question

Хвост динозавра в два раза длиннее его тела,а длина тела равна половине длины его шеи,которая составляет 12 метров

Answer 1

Длина тела равна  12/2=6 метров 
длина хвоста равна  6*2=12 метров
если нужно узнать всю длину динозавра от шеи до хвоста,то 12+6+12=30 метров

Answer 2

Dinosaur Tail Length Calculation

The length of the dinosaur's body is equal to half the length of its neck, which is 12 meters. The length of the tail is twice the length of the body.

Calculating the Lengths: The length of the neck = 12 meters The length of the body = 12 / 2 = 6 meters The length of the tail = 6 * 2 = 12 meters

Conclusion

Based on the given information, the length of the dinosaur's body is 6 meters, the length of its tail is 12 meters, and the length of its neck is 12 meters.
