Need to find the smallest value for a rectangle with 40m² area.Hi. #2 20120803 23:09:57
Re: Need to find the smallest value for a rectangle with 40m² area.hi draketcg If you try to solve that using the quadratic formula: There are no real values of x to solve that square root so it would seem it is not possible. To find the biggest area I'll make a graph first : You can see from the graph ( at the end ) that the maximum is below 40, so that confirms the statement above. Quadratics are symmetrical so the maximum will be at x = 6 Or use calculus to find the maximum. So biggest area = 6(126) = 36 Bob You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei #4 20120803 23:26:48
