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?

2(H + W) = 100
H + W = 50
Area = W*H = W*(50W) = 50W  W^2
= +625  (W25)^2
This is a maximum when the width W = 25, in which case the height H is also 25. The maximumarea figure is a square.
