# Constraint Equation.

A rectangular garden of area 532 square feet is to be surrounded on three sides by a brick wall costing

$14 per foot and on one side by a fence costing$5 per foot. Find the dimensions of the garden such that the cost of the materials is minimized.

Eliminate L from the following objective equation using the above constraint equation.

1. C = 14 ( W+2L ) + 5W
2. C(W) = 19( W + 784/W )

This is a step in solving my problem in my textbook. However I am confused as to how 784 came into the equation. What was multiplied to get it?
