The length of a rectangle is fixed at 24 cm. What widths will make the perimeter greater than 7c cm?

The width must be greater than:

  • algebra -

    must be a typo
    since the length is 24 cm, the perimeter must be greater than 48 cm

  • algebra -

    Sorry it said greater than 76 cm not 7c.

  • algebra -

    2L + 2W < 76

    Insert your value for L and solve for W.

    I hope this helps.

  • algebra -

    Thanks I think it did...just to be sure:

    2(24) +2w< 76
    48 +2w <76
    2w < 28
    w < 14

    So the answer would be 14
