xy = 32 makes y = 32/x
z² = (32/x)² + (x/2)²
<span>Isolate z
</span>z = 32/x + x/2
Find dz/dx
fr(z) = (x² - 64)/ (2x²)
<span>Set z' = 0, algebraically solving for x having
</span>x +- 18
<span>Since you cannot have a dimension of -8, the only answer for x is 8.
</span>
<span>Go back to the original area equation; 32 = xy and plug in x making
</span><span>32 = 8y
</span><span>y = 4</span>
