Answer 2

Answer:

• 90/7

Step-by-step explanation:

As per the information provided in the question, We have :

• Each side of an equilateral triangle = 4 2/7 m

We are asked to find the perimeter of the triangle.

Firstly, We will the convert the value of side into improper fraction as it is in the form of mixed fraction.

• 4 2/7 = 30/7

In this question, As we know that, Perimeter of a triangle is product of three sides. So, We will multiply the side with 3. The resultant will be the perimeter of the equilateral traingle.

It is given by –

$\begin{gathered}\longmapsto \bf Perimeter_{(triangle)} = 3 \times Side\end{gathered}$

Putting the value of side,

$\begin{gathered}\longmapsto \rm Perimeter_{(triangle)} = 3 \times \dfrac{30}{7} \end{gathered}$

Multiplying the numbers,

$\begin{gathered}\longmapsto \rm Perimeter_{(triangle)} = \dfrac{90}{7} \end{gathered}$

∴ The perimeter of the equilateral traingle is 90/7.

★ Formulas related to it :

• Perimeter of Square = 4 × side

• Perimeter of Triangle = sum of its all sides

• Perimeter of Circle = 2πr (r = radius)

• Area of Square = (side)²

• Area of Right angle triangle = 1/2×b×h (b = base , h = height)
