The perimeter of the state of Wyoming is 1280mi. The width is 90mi less than the lenght. Find the width and the length.

I don't know what formula to use or how to write it.

Perimeter = length + length + width + width = 1280 miles
OR P = 2L + 2W = 1280 miles (equation 1)

width + 90 miles = length
OR W + 90 = L (equation 2)

You have two equations and two unknowns. Solve for W and L.

I am trying to work this out and I am not getting

W=595 L=685

he is right
