Name the lenghts of the sides of three rectangles with a perimeter of 12 units use whole numbers only. I don't understand the question

    The questions is telling you that there are three possible rectangles whose perimeter is 12 units and whose sides are whole numbers in length.

    The perimeter of a rectangle is given by 2(L+B).

    So, this means that L+B = 6.

    What whole numbers add up to 6?

    1+5 = 6
    2+4 = 6
    3+3 = 6

    And those are your rectangles. One has sides of 1 and 5 units, the second has 4 and 2 unit sides and the third is a square with a 3 unit side.

  • math -

    Each rectangle has a perimeter of 12 units.

    P = 2L + 2W

    12 = (2 * 4) + (2 * 2)

    12 = (2 * 3) + (2 * 3)

    Can you think of the possible dimensions of a third rectangle?
