B 3 km C D 3 km A a) Formulate an expression L(h) for the total length of ditch. L(h) = 2(h^2+(1.5)^2)+(3-h) (2 points.) h b) Now calculate the value of h which minimizes the amount of ditch to be dug. If there is more than one such value give your answer as a comma separated list. X P W 1 B 3 km C D 3 km A a) Formulate an expression L(h) for the total length of ditch.
