DCP-505: Covert Operation Back to All Problems

Easy Geometry > Basic Geometry

Famous [**IGI**][1] agent **David Jones** is now on a covert mission of rescuing his base intelligence reporter **Anya**. Enemies kidnapped Anya about a few hours ago. <br> Looking towards the map he figured out that the enemy base can be characterized as an **isosceles right triangle**. An isosceles right triangle is such a **right triangle** whose, **base and height** will be off **same length**, and **hypotenuse** will be off **different length**.<br> The map usually displays the **perimeter** (summation of the length of all three sides) of that triangle. Jones has to find the area of that triangle to install some C4 mine and save Anya. Jones does not have a calculator. Would you please do that for him? He will pay you nothing btw!! :-P Input: ------ Input starts with an integer **T**, which denotes the number of test cases.<br> The next **T** lines contain an integer **P**, which denotes the perimeter of an isosceles right triangle. Constraints: ----- 1 <= **T** <= 5001<br> 1 <= **P** <=10^9 Output: ------- For each test case, you need to print the area of the triangle **exactly 2 places** after the decimal point. Sample Input ------------ 1 40 Sample Output ------------- 68.63 [1]: https://en.wikipedia.org/wiki/Project_I.G.I.:_I%27m_Going_In
