Answer:
Find the value of x:-
To find Y, use Pythagorean theorem:- ![c^{2} =a^{2} +b^{2}](https://tex.z-dn.net/?f=c%5E%7B2%7D%20%3Da%5E%7B2%7D%20%2Bb%5E%7B2%7D)
![(2.1)^{2} =y^{2} +(1.4)^{2}](https://tex.z-dn.net/?f=%282.1%29%5E%7B2%7D%20%3Dy%5E%7B2%7D%20%2B%281.4%29%5E%7B2%7D)
![2.1^{2}=4.41](https://tex.z-dn.net/?f=2.1%5E%7B2%7D%3D4.41)
![1.4^{2} =1.96](https://tex.z-dn.net/?f=1.4%5E%7B2%7D%20%3D1.96)
![4.41=y^{2} +1.96](https://tex.z-dn.net/?f=4.41%3Dy%5E%7B2%7D%20%2B1.96)
subtract 1.96 from both sides
![2.45=y^{2}](https://tex.z-dn.net/?f=2.45%3Dy%5E%7B2%7D)
![y=1.5652](https://tex.z-dn.net/?f=y%3D1.5652)
Now, to find x:-
![x=y+y](https://tex.z-dn.net/?f=x%3Dy%2By)
![= 1.5632+1.5652](https://tex.z-dn.net/?f=%3D%201.5632%2B1.5652)
![x=3.1 \: ft](https://tex.z-dn.net/?f=x%3D3.1%20%5C%3A%20ft)

That is 2015! or 2015 factorial
that is big
not sure if a joke but the answer is (see attachment)
