An Artist has 600 inches of framing material to form a rectangular frame. The dimensions of the wall on which it will hang limit
kondor19780726 [428]

Answer:

  • 2(L +W) ≤ 600
  • W ≤ 200
  • L ≥ 2W

Step-by-step explanation:

We assume the problem wording means the length is to be at least 2 times <em>as long as</em> the width. (<em>Longer than</em> usually refers to a difference, not a scale factor.)

If we let "W" and "L" represent the width and length, respectively, then we can translate the problem statement to ...

  2(L + W) ≤ 600 . . . . . . the perimeter is twice the sum of length and width

  W ≤ 200 . . . . . . . . . . . . the width is at most 200 inches

  L ≥ 2W . . . . . . . . . . . . . the length is at least twice the width
