Question

two sides of a rectangular are 12 cm and 14 cm the perimeter of the triangle is 36 cm what is the length of third side​

Answer 1

$\large \boxed{ \sf { \red{S}}} \boxed{ \sf{ \blue{o}}} \boxed{ \sf{ \pink{l}}} \boxed{ \sf{ \purple{u}}} \boxed{ \sf { \red{t}}} \boxed{ \sf{ \green{i}}}\boxed{ \sf{ \pink{o}}}\boxed{ \sf{ \blue{n}}}$

$\sf~~~$

$\sf{Perimeter = Sum \: Of \: all \: Sides}$

$\sf36 = a + b + c$

$\sf36 = 12 + 14 + c$

$\sf36 = 26 + c$

$\sf{c = 10 }$

$\sf~~~$

$\large{ \boxed{ \rm{ \red\therefore{ \red{Value \: Of \: C \: is \: 10 \: cm}}}}}$

Answer 2

Perimeter=Sum of all sides

36 cm=a+b+c

36 cm=12+14+c

36 cm=26+c

c=36-26

c=10
