Answer 1

Step-by-step explanation:

25.5 cm

hope it will work answer is write

Answer 2

$\rm \rightarrowtail \: Perimeter_{(Triangle)}=a+b+c$

$\rm \rightarrowtail \: Perimeter_{(Triangle)} = 8 + 12 + 30 = 50cm$

$\rm \rightarrowtail \: Semi - Perimeter_{(Triangle)} = \dfrac{1}{2}×Perimeter$

$\rm \rightarrowtail \: Semi - Perimeter_{(Triangle)} = \dfrac{1}{2}×50$

${ \boxed{ \frak {\pink{\: Semi - Perimeter_{(Triangle)} = 25cm}}}}$
