plz say fast..​

Answer 1

Answer:

1.7677 cm

Step-by-step explanation:

There is a relation as A = Pr/2,

where A area of the triangle

P is its perimeter, and

r is the inradius.

Here P = 6+11+15 = 32

s = P/2 = 16

A by Heron’s equation = [16(16–6)(16–11)(16–15)]^0.5

= [16*10*5*1]^0.5

= 28.2842 sq cm

r, in cm = 2*28.2842/32

= 1.7677 cm.
