The perimeter of a recatangle is twice the sum of its length and its width. The perimeter is 16 meters and its length is 2 meters more than twice its width.What is the length?

asked by Odessa
  1. w = width
    (2+2w) = length
    perimeter = 2[w+(2+2w)] =16
    w+2+2w = 8
    3 w = 6 etc

  2. 16 = 2L + 2W)
    L = 2W + 2.

    Solve the two equations for L and W.

    By substitution, you can see that

    16 = 2L + L - 2 = L - 2

  3. The ratio of men to women in a certain factory is 3:4. There are 210 men. How many workers are there?

  4. Answer is 280

    x = (4/3) * 210 = 280

  5. M/W = 3/4
    M = 210
    W = 280
    M + W = ?

    The number of women is 280, but the total number of workers is something else.
