Question

if the area of an equilateral triangle is 4 root 3 cm^2, then its perimeter is

Answer 1

Step-by-step explanation:

Given that side of equilateral triangle is 4

3

cm

Perimeter of equilateral triangle=3× side

=3×4

3

=12

3

⇒ Perimeter is an irrational number

Now, Area of equilateral triangle =

4

3

side

2

=

4

3

×(4

3

)

2

=12

3

⇒ Here, Area and Perimeter have same numerical value
