Question

If the perimeter of an equilateral triangle is 15 cm. Find it’s side

Answer 1

Answer:

Hence the side of the equilateral triangle is 5 cm.

Step-by-step explanation:

According to the information provided in the question.

It is stated in the preceding question that,

The presented information is perimeter of an equilateral triangle is 15 cm.

We need to find the side of equilateral triangle.

The formula of perimeter of the equilateral triangle is as bellow,

$P=3a$

Where a is the side of the triangle,

So, the side of the triangle will be,

$3a=P\\a=\frac{P}{3}$

Substitute the value of perimeter in the above equation we get,

$a=\frac{15}{3}$

Dividing both numerator and denominator with 3 we get,

$a=\frac{5}{1}\\a=5cm$

Hence the side of the equilateral triangle is 5 cm.
