The equation for the perimeter of a rectangle is P = 2L + 2W.
Equation 1:
Equation 2:
Plug (W + 26) into equation 1 for L.
Multiply the 2 through.
Combine like terms.
Subtract 52 from both sides.
Divide both sides by 4.
Now plug 67 into equation 2 for W and solve for L.
Equation 2:

Width = x
Length = x + 26
Perimeter = 2*length + 2*width
320 = 2*(x + 26) + 2x
320 = 2x + 52 + 2x
320 = 4x + 52
320 - 52 = 4x
4x = 268
x = 67.
Width = 67 feet
Length = 93 feet.
