Answer 1

Answer:

your answer is 11 cm(please follow me and mark my answer as brainilist answer) please

Step-by-step explanation:

perimeter =(11+6+5)=22

semi perimeter = 22÷2=11

Answer 2

Answer:

Use heron's formula

Step-by-step explanation:

semi perimeter, s = a+b+c/2

s=15+11+6/2

s= 16

Heron's formula :

Area of triangle = √s(s-a)(s-b)(s-c)

where a,b,c are sides of triangle.

In the above question,they just asked us to find only semi perimeter.So its not needed to apply complete heron's formula by finding both semiperimeter and area of triangle.I mentioned complete formula for ur better understandig dear.....!

So just write the semi perimeter part.

Hope it's helpful to u !!!

Pls make me brainliest dear!!!
