What is the difference of 18 square feet and half of 18?
18 square feet is an area, and half of 18 = 9 is a number. You can't compare numbers with areas (or any measurement with units).
Is 18 a square number why or why not?
It is a square number but not a perfect square. The nearest perfect squares, on either side, are 4^2 = 16 and 5^2 = 25. Since there is no integer between 4 and 5 and the square is a strictly monotonic function, 18 cannot be a perfect square.
