Question

The semi perimeter of a triangle is half of the perimeter. For the triangle below the semi-perimeter is (a+b+c)/2. What is the ratio of the side of an equilateral triangle to its semi-perimeter?​

Answer 1

Answer:

Let the side of an equilateral triangle be x.

So the sides are all x as equilateral triangle's all sides have same length.

Semi perimeter here -

$\frac{x+x+x}{2}$

= $\frac{3x}{2}$

= $1.5x$

So the ratio is 1 : 1.5
