A = 4,
we denote one side of the rectangle with
a
, and the other with
b
we can write, that:
a
⋅
b
=
16
so we can write, that
b
=
16
a
Now we can write perimeter
P
as a function of
a
P
=
2
⋅
(
a
+
16
a
)
We are looking for the smallest perimeter, so we have to calculate derivative:
P
(
a
)
=
2
a
+

P

(
a
)
=

−

a

−

a

The extreme values can only be found in points where
P
'
(
a
)
=
0
P
'
(
a
)
=
0
⇔

or

Since, length is a scalar quantity, therefore, it cannot be negative,
When

b
