Question

यदि (S-a) = 5 सेमी (S-b) = 10 सेमी (S-c) = 1 सेमी तो s
ज्ञात कीजिए​

Answer 1

Step-by-step explanation:

Here s stands for semi perimeter..

Perimeter is the sum of all sides of A figure.

now let us consider

(s-a) =5 as eqn 1

(s-b) =10 as eqn 2

(s-c) =1 as eqn 3

now adding all the three eqns we get

3s-a-b-c=5+10+1

3s-(a+b+c) =16

3s-(s/2) =16

taking lcm

(6s-s) /2=16

5s=32

S=32/5
