Question

Choose the perimeter of a triangle with sides measuring 11cm,13cm and 15 cm.​

Answer 1

Question:-

• Find the Perimeter of triangle whose sides are 11cm , 13cm and 15cm.

Given:-

• Side = 11cm
• Side = 13cm
• Side = 15cm

To Find:-

• Perimeter of triangle

Solution:-

Just apply the Formula to find the perimeter

$\begin{gathered}\begin{gathered}: \implies \underline{ \boxed{\displaystyle \sf \bold{\: Perimeter\: of \: Triangle \: = \: Side \: + \: Side \: + \: Side }} }\\ \\\end{gathered}\end{gathered}$

Putting the Values

$\begin{gathered}\begin{gathered}: \implies \displaystyle \sf \: Perimeter\: of \: Triangle \: = \: 11cm\: + \: 13cm \: + \: 15cm \\ \\ \\\end{gathered}\end{gathered}$

$\begin{gathered}\begin{gathered}: \implies \displaystyle \sf \: Perimeter\: of \: Triangle \: = \: 24cm\: + \: 15cm \\ \\ \\\end{gathered}\end{gathered}$

$\begin{gathered}\begin{gathered}: \implies \displaystyle \sf \: Perimeter\: of \: Triangle \: = \: 39cm\\ \\ \\\end{gathered}\end{gathered}$

$\begin{gathered}\begin{gathered}: \implies \underline{ \boxed{\displaystyle \sf \bold{\: Perimeter\: of \: Triangle \: = \: 39cm }} }\\ \\\end{gathered}\end{gathered}$

So, the Perimeter of Triangle = 39cm
