Answer 1

✤✤✤✤✤✤✤✤✤✤✤✤✤✤✤✤✤✤✤✤✤✤

We know that,

$s \: = \frac{a + b + c}{2}$

Given that,

s= 13

a = 18

b = 7 and

c = ?

putting values in the formula

$13 = \frac{18 + 7 + c}{2} \\ \\ 13 \times 2 = 25 + c \\ \\ 26 = 25 + c \\ \\ c = 26 - 25 \\ \\ c = 1$

Hence your answer is 1

I. e, c = 1

Answer 2

Answer: chapter : heron's formula

Step-by-step explanation:

s = 13

a = 18

b = 7

c = ?

s = a + b + c

13 = 18 + 7 + c

13 = 25 + c

13 - 25 = c

c = 12
