She Bought 23 shirts because if you do 400-50 you get 350 the / by 15 wich give you 23.333333ect
(9x - 1)² = <em>81x² - 18x + 1</em>
Hence the maximum possible area is 2500 square meteres
Given the area of the rectangular garden expressed as;

The maximum area occurs when dA(x)/dx = 0

Next is to get the maximum area possible. Substitute x = 50 into the original function as shown;

Hence the maximum possible area is 2500 square meters
