A rectangular field is 35 m longer than it is wide. The length of the fence around the
perimeter of the field is 290 m. What are the dimensions (length and width) of the
fence?

you put 390 instead of 290 for the perimeter why? it has me a bit confused.

Oops! I'm sorry. That was a typo.
P = 2L + 2W
290 = 2(W + 35) + 2W
290 = 2W + 70 + 2W
220 = 4W
55 = W
