Answer 1

Answer:

Step-by-step explanation:

❇

✔So, the area of given equilateral triangle is 15.588 cm²

Solution ❇

____________€€€€€____________€€€

Given - Each side of the equilateral triangle = 6 cm

Area of the equilateral triangle = √3/4 × a² (Where a = side of the equilateral triangle)

⇒ √3/4 × (6)²

⇒ (1.732 × 36)/4

⇒ 1.732 × 9

⇒ 15.588 cm²

Answer 2

Answer:

Hence the perimeter of the equilateral triangle is 18 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 6 cm.

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 6cm in the above equation we get,

$P=3\times 6\\P=18cm$

Hence the side of the equilateral triangle is 18 cm.
