College Algebra

Translate the problem into a pair of linear equations in two variables. Solve the equations using either elimination or substitution. State your answer for both variables.
The perimeter of a rectangle is 72m. If the width were doubled and the length were increasd by 9m, then the perimeter would be 114m. What are the dimentions?

asked by Ashley
  1. 2L+2W=72
    2(2W) + 2(L+9)=114

    check that.

  2. Does this mean that the dimentions are 72 and 114 or do you take it father to find what w & l are which I think might be w=12 and l=24. does that sound right?

  3. Of course you have to find width w, and length L.

    I would go back and check W=12, L=24 in the original equations. If they check, you are home bound.
