Question

What is the smallest perimeter possible for a rectangle whose area is 16in^2 and what are its dimensions?

Answer 1

Area = length * width
Perimeter = 2*length + 2*width
= 2*length + 2*Area/length
= 2(length + 16/length)
Now, differentiate it and set to zero to find length. Then, find width using area formula.
