Rajat has a rectangle of integer side lengths a and b, and area 1000. What is the smallest perimeter it could have?
To minimize the sum of the side lengths, we need to keep the length and width as close as possible, because the square has the smallest perimeter of all rectangles with a fixed area. So, 40 and 25 multiply to 1000 and are as close as possible – the 40 x 25 rectangle has perimeter 130.
