describes the requirements of the facility.

(b) Find two solutions of the system and interpret their meanings in the context of the problem.

    a) Since the track must be 125 meters long, therefore. 

    2x + πy ≥ 125

    Since the area of the exercise must be at least 500 sq meters , therefore .

    xy ≥ 500

    Also, x and y are positive. Therefore, the system of inequalities is 

    2x + πy ≥ 125

    xy ≥ 500

    x  ≥  0

    y  ≥  0

    Take the above 2x + πy ≥ 125 and xy ≥ 500 and graph it. I don't have a program to do graphs sorry. 

    let the y axis be 10 20 30 40 50 60 and the x axis be 10 20 30 40 50 60. plug it in your equations .
