Question

Find the semi perimeter of a triangle with sides 8cm , 12cm and 30cm​

Answer 1

Answer:

here goes your ans...

Step-by-step explanation:

since, sum of all side is equal to perimeter

so that, 8cm + 12cm + 30cm =50 cm

so that semi perimeter =1/2 x perimeter

= 1/2x 50cm

= 25cm

so that semi perimeter = 25cm

Answer 2

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

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

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

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

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