                <em>The side length of an equilateral triangle is 5 cm. Find its perimeter.</em>

\dashrightarrow\large\textsf{\textbf{\underline{Answer and how to solve:-}}}

We are given that the triangle is equilateral.

"equi" means "equal" and "lateral" means "sides"

✯ So an equilateral triangle has 3 equal sides.

We are also given that one side is equal to 5 cm.

If one side is equal to  5 cm, and the triangle's equilateral, then the other two sides are equal to 5 cm.

◈ In order to find the perimeter of a shape, you should add all of its side lengths together.

✯ Now, we need to find the perimeter, which we can find using the following formula:-

\bold{Perimeter_{(triangle)}=a+b+c}

  • Where a, b, and c are side lengths of the triangle.

Now, we add them:-

\hookrightarrow\sf{P=5+5+5}

So we conclude that the perimeter is equal to:-

\hookrightarrow\sf{P=15\:cm}

<h3>Good luck with your studies.</h3>
