If the perimeter of a rectangle is 318 inches, find the width and length. what's the answer?

If those Length and Width are consecutive integers then we can calculate the answer by following:

let's consider that Length is n

Then width will be n+1

Perimeter of rectangle is equal to 2 * (L+W) in this case

P = 2 * (n + [n + 1]) = 2 * (n + n + 1) = 2 (2n + 1)

P = 318

318 = 2 (2n+1)

159 = 2n+1

159 - 1 = 2n

158 = 2n

79 = n

So this means that Length is 79 and Width is 80

or vice versa, Length is 80 and Width is 79

Is there any other known values?
