Question

Find the perimeter of an equilateral triangle whose each side is 10 cm.
​

Answer 1

Answer:

as we know that all the sides of an equilateral triangle are same so....S=10cm...Perimeter =S1+S2+S3, putting the value of S in the formula of perimeter- 10+10+10..therefore the answer is 30cm

Answer 2

Answer:

Hence the perimeter of the equilateral triangle is 30 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 side of an equilateral triangle is 10cm.

We need to find the perimeter of equilateral triangle.

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

$P=3a$

Where a is the side of the triangle,

Substitute the value of side that is 10cm in the above equation we get,

$P=3\times 10\\P=30cm$

Hence the perimeter of the equilateral triangle is 30 cm.
