Can you find all the rectangles for which the perimeter equals twice the area? (just the numbers. Ignore the fact that the units don’t match)

    Use (L)/(L – 1) = W to generate values of the width for different values of W. Or simply graph it. Did you want integers?…

    2, 2
    3, 1.5
    4, 1.3…
    5. 1.25

    And so on?
