Solution :
By observing diagram clearly we can observe that there is a right angled triangle with :
- Base, B = 3
- Perpendicular, P = 3
- Hypotenuse, H = c
So, to find hypotenuse, let's use Pythagoras' theorem :
[tex] \large \underline{\boxed{\bf{H^2 = B^2 + P^2}}}[/tex]
[tex] \tt : \implies c^2 = 3^2 + 3^2[/tex]
[tex] \tt : \implies c^2 = 9 + 9[/tex]
[tex] \tt : \implies c^2 = 18[/tex]
[tex] \tt : \implies c = \sqrt{18}[/tex]
Hence, value of c is √18.
