Answer 2

$\tt\large{\hookrightarrow Given}$

${\sf\bold{AC~=~6cm}}$

${\sf\bold{AB~=~3cm}}$

$\tt\large{\hookrightarrow To~find}$

${\sf\bold{BC}}$

$\tt\large{\hookrightarrow Solution}$

$\fbox\green{PYTHAGORAS~THEORAM~→~(AC)²~=~(AB)²~+~(BC)²}$

$\rm{\dashrightarrow (6)²~=~(3)²~+~(BC)²}$

$\rm{\dashrightarrow 36~=~9~+~(BC)²}$

$\rm{\dashrightarrow (BC)²~=~27}$

$\rm{\dashrightarrow BC~=~√27}$

$\rm{\dashrightarrow BC~=~3√3~cm}$
