give the dimensions of rectangles with perimeters of 70ft and length to width ratios of 3to4 4to5 and 1to1

  • math -

    The 1:1 case is obviously a square, with length and width both equal to 70/4.

    Try the others yourself.

    If (width)/(length) = 3/4,

    L = (4/3)W
    70 = 2(L + W) = (14/3)W

    Solve for W
