Question

If 'l' be the side of an equilateral triangle, its perimeter is given by
​

Answer 1

Answer:

Correct answer:

The length of the equilateral triangle's side is the length of the hypotenuse of the 30-60-90. Using this ratio, we find that the length of this triangle's hypotenuse is 4. Thus the perimeter of the equilateral triangle will be 4 multiplied by 3, which is 12.

Answer 2

Answer:

given that

side of the equilateral triangle=l

In equilateral triangle all sides are equal

∴ side 1=side 2=side 3.

So, perimeter=l+l+l

=3l
