Homework Statement
1000m^2 garden. 3 sides made of wooden fence. 1 side made of vinyl(costs 5x as much as wood).
Length cannot be more than 30% greater than the width.
Find the dimensions for the minimum cost of the fence.
Homework Equations
1000 = LW
C = 2L + W + 5W
The Attempt at a Solution
Attempted ignoring the restriction. Answer does not meet restriction. Solved algebraically for the only rectangle where L = 1.3W and L = 1000/W. It is a calculus question and it is therefore suspected that this is not the answer. The minimum cost is not necessarily when the vinyl side is minimal.
