14 cm

none of these 



​

Answer 1

Answer:

12cm

Step-by-step explanation:

• semi perimeter= (6+8+10)/2= 24/2= 12cm

Hope you got the answer:)

Answer 2

$\underline{\underline{\green{\textbf{Step - By - Step - Explanation : -}}}}$

To Find :

• Semi - perimeter of Triangle

Sᴏʟᴜᴛɪᴏɴ :

• Sides of Triangle are 6cm ,8cm and 10cm
• Semi perimeter = ?

$\sf \red{semi \: perimeter \: of \: \triangle \: = \frac{a + b + c}{2} }$

where, a ,b and c are seides of Triangle.

• a = 6cm
• b = 8cm
• c = 10cm

$\sf \dashrightarrow \: \frac{6 \: cm \: + \: 8 \: cm\: + \: 10 \: cm}{2} \\ \\ \sf \dashrightarrow \: \cancel\frac{24}{2} \\ \\ \sf \dashrightarrow \: 12 \: cm$

$\large\dag \large { \red{\underline{\bf{Hence }}}}$

• Semi - perimeter of Triangle is 12cm
