How many different rectangles can you make so that each one has a perimeter of 16 inches?

  • Math(geometry) -

    Formula for perimeter,
    P = 2L + 2w

    2L + 2w = 16
    2(L + w)= 16
    L + w = 8

    You need numbers that add to 8.
    8 + 0 = 8
    7 + 1 = 8
    6 + 2 = 8

    See how many you can come up with.

    There might be any easier way, that I'm not thinking about.

    Good luck

    Cross off 8 + 0 = 8.
    Can't have a side of 0.
