Question

Find the perimeter of an equilateral triangle with its side measuring 7.2 m.​

Answer 1

Answer:

Perimeter of an equilateral triangle is $21.6$ m.  

Step-by-step explanation:

Given : Length of side of equilateral triangle = $7.2$ m

To find : Perimeter of triangle = ?

Solution :

• It is given that the length of side of equilateral triangle = $7.2$ m
• We have to find the perimeter of an equilateral triangle.
• We know that the length of all sides of an equilateral triangle is same.
• Perimeter of a triangle is the sum of all sides of an triangle.
• Now, triangle has three sides and a length of one side is $7.2$ m.

           Perimeter of a triangle = sum of all sides

                                            = $7.2+7.2+7.2$

                                            = $21.6$ m

• ∴ Perimeter of an equilateral triangle is $21.6$ m.
