A rectangular field is four times as long as it is wide. if the perimeter of the field is 340 yards, what are the field's dimensions

Let the width of the field = x.

Then the length = 4x

Now the perimeter = 2 * length + 2 * width, so we have the equation:-

2*4x + 2x = 340

8x + 2x = 340

10x = 340

x = 34 yards = width

4x = length = 136

Answer: the width is 34 yards and length is 136 yards.
