write a quadratic function needed to find the dimension of the rectangle with perimeter 100 having the maximum area. what are the dimensions of the rectangle with the maximum area?

  • math (college) - ,

    2(H + W) = 100
    H + W = 50

    Area = W*H = W*(50-W) = 50W - W^2
    = +625 - (W-25)^2
    This is a maximum when the width W = 25, in which case the height H is also 25. The maximum-area figure is a square.
