Question

a triangle has sides measuring 15 cm , 19 cm and 23 cm .find its perimeter​

Answer 1

Step-by-step explanation:

peremeter= 15+19+23=57

Answer 2

Given

• The sides of the Triangle.

To find

• We have to find the Perimeter of the Triangle.

$\sf\pink{As \ we \ know \ that}$

If the three sides of the Triangle are different so, it is known as Scalene Triangle

${\fcolorbox{blue}{black}{\purple{\:\: Perimeter \ of \ Scalene \ Triangle \= Sum \ of \ length \ of \ it's \ sides\:\:}}}$

Therefore,

Perimeter ⇒ $\sf\green{15cm + 19cm + 23cm}$

Perimeter ⇒ $\sf\red{57cm}$

•°• $\sf\blue{Hence,\ verified \ that \ the \ Perimeter \ of \ the \ Triangle \ is \ 57cm}$

Diagram of Triangle

$\setlength{\unitlength}{1 cm}\begin{picture}(0,0)\thicklines\qbezier(1, 0)(1,0)(3,3)\qbezier(5,0)(5,0)(3,3)\qbezier(5,0)(1,0)(1,0)\put(2.85,3.2){ \bf A }\put(0.5,-0.3){ \bf B }\put(5.2,-0.3){ \bf C }\end{picture}$

• In Diagram AC = 15cm
• In Diagram CB = 19cm
• In Diagram BA = 23cm

More to know:-

• A triangle with three sides different is known as $\sf\pink{Scalene \ Triangle}$

• A triangle with two equal sides is known as $\sf\purple{Isosceles \ Triangle}$

• A triangle with all same sides is known as $\sf\green{Equilateral \ Triangle}$

• Perimeter of Scalene Triangle = Sum of the length of all sides.
