Answer 2

$\large \bold{ \red{ \underline{Question}}}$

To verify Euler's formula for the given figure.

$\large \bf{ \color{blue}{ \underline{Solution}}}$

L.H.S = F + V - E = 2 = R.H.S

L.H.S = 11 + 9 - 16 = 2 = R.H.S

L.H.S = 18 - 16 = 2 = R.H.S

L.HS = 2 = 2 = R.H.S

L.H.S = R.H.S

Hence, Verified
