The area of the square is 2x times 2x which is 4x^2. The circular pond's area is pir^2 which is x^2pi. The remaining space for flowers is 4x^2-x^2pi. If you factor out the x^2 you get x^2(4-pi).

The area of the land is 4X^2, the area of the pond is (pi)X^2, so the remaining area should be 4X^2 - piX^2

area of circle = pi r^2 : pi x^2
area of square = s^2 : (2x)^2 = 4 x^2
area not covered by pond = s^2 - (pi r^2) : 4 x^2 - (pi x^2)
= (4 - pi) x^2
