Question

The perimeter of an equilateral triangle is 37.5cm. Find length of the side.​

Answer 1

Answer:

12.5

Step-by-step explanation:

Perimeter of equilateral triangle = 37.5÷5=12.5

hence 12.5 is the answer

Answer 2

Answer:

Hence, value of length of side of equilateral triangle will be 12.5 cm

Step-by-step explanation:

In context to question asked,

We have to determine the length of side of equilateral triangle.

As per question,

We have,

Perimeter of triangle = 37.5 cm

As we know that,

• All the sides of equilateral triangle are same.

• The perimeter of equilateral triangle can be determined by adding the length of all the sides.

As we have,

Formula for determining the perimeter of equilateral triangle as,

$Perimeter = side +side +side = 3 \times side$

So, for determining the value of length of side of equilateral triangle,

We will put the value of perimeter of triangle given in the question in above formula,

Thus we will get,

$Side = \frac{Perimeter}{3}\\=>Side = \frac{37.5}{3} = 12.5\:cm$
