A rectangular storage tank with an open top is to have volume (20 m'). The length of the base is twice the width, see the figure. The Material of the base costs (20 S) per square meter. The material of the sides costs (10 $) per square meter. Use Lagrange multiplier method to find the optimum dimensions of a tank that give the minimum cost. Ans/ I-3.914 w 1.957 h = 2.61
