Answer 2

$\huge\bf\underline\red{Full question}$

Two sides of triangle are 13 cm and 14 cm and its semi perimeter is 18 cm find the third side of triangle?

$\huge\sf\underline\red{Given:-}$

a = 13cm

b = 14 cm

Semi perimeter is 18 cm

$\huge\bf\underline\red{To find:-}$

Third side of a triangle

$\huge\sf\underline\red{Formula}$

Semi perimeter= $\frac{a + b + c}{2}$

$\huge\bf\underline\red{solution}$

Let the other side be c

Therefore

$\frac{13 + 14 + c}{2}$ = 18

$\frac{27+c}{2}$=18

27cm + c = 36 cm

c= 9cm

$\huge\sf\underline\red{Conclusion}$

Third side of triangle is 9cm
