What value should come in place of question mark(?) in the following equation?
$$360\sqrt?$$ + 4500 = 19700 - 9800
$$360\sqrt?$$ + 4500 = 19700 - 9800
$$\Rightarrow 360\sqrt? + 4500 = 9900$$
$$\Rightarrow 360\sqrt? = 5400$$
$$\Rightarrow \sqrt? = 15$$
$$\Rightarrow ? = 15^2$$
$$\Rightarrow ? = 225$$
