The Plessy v. Ferguson case of 1896 ruled out that segregation was constitutional as long as both blacks and whites enjoyed opportunities that were separate but equal.
However, the Supreme Court's verdict in the Plessy v. Ferguson case of 1896 was challenged by Justice Earl Warren stating that the idea of ‘separate but equal’ in public school was unconstitutional and inherently unequal.
Thus, Chief Justice Earl Warren issued the Supreme Court’s unanimous decision in Brown v. Board of Education, ruling that racial segregation in public schools violated the "Equal Protection Clause” of the 14th Amendment.
P = 2x+2(450-x)=900 A = x(450 - x) A = x(450 - x) -x² + 450x = A -x² +450x = A A is going to be maximum, when x is a vertex. -(x² - 450x) = A -(x² - 2*225x+225²) - 225² =A -(x-225)² -225² = A Vertex when x=225
