Answer 2

Answer :

Perimeter of the triangle is 27cm.

Step-by-step explanation :

Question says that, three sides of a triangle are the in ratio 2 : 3 : 4. The shortest side measures 6cm. Find the perimeter.

Step 1 : Let's assume the three sides :

➪ $2x$

➪ $3x$

➪ $4x$

Step 2 : Calculate the value of $x$ :

The shortest side is $2x$

$\begin{gathered}{\underline {\boldsymbol{According \: to \: the \: question}}} \end{gathered}$

$\implies 2x = 6$cm.

$\implies x = \dfrac{6}{2}$

$\implies x = \bf 3cm.$

The value of $x$ is 3cm.

Step 3 : Calculate the actual three sides :

➪ $2x$ = 2(3) = 6cm.

➪ $3x$ = 3(3) = 9cm.

➪ $4x$ = 4(3) = 12cm.

Step 4 : Find the perimeter :

Perimeter of a △ :

→ sum of all sides

→ 6 + 9 + 12

→ 27cm.
