The sum of perimeter of a square and circumference of a circle is given. Prove that the sum of their areas will be minimum when the side of square is equal to the diameter of the circle.

If the side of a square is doubled, then the area of the square

Given the sum of the perimeters of a square and a circle,show that the sum of their areas is least when one side of the square is equal to diameter of the circle.

Area of a square is doubled if the side of the square is doubled.

A wire of length l is cut into two parts. One part is bent into a circle and the other into a square. Prove that the sum of the areas of the circle and the square is the least, if the radius of the circle is half of the side of the square.
