A rectangular field is twelve times as long as it is wide. If the perimeter of the field is 2340 feet, what are the dimensions of the field?

Answer: Width - 90 feet, Length - 1080 feet
Step-by-step explanation:
Let the width = x.
Then the length = 12x.
The perimeter is 2 * (width + length)
2340 = 2*(x+12x)
1170 = 13x
x = 90.
Therefore, the width = 90 feet and the length = 1080 feet
