Question

The side of an equilateral triangle is 14 cm. find its height and area.​

Answer 1

Step-by-step explanation:

Given :

The side of an equilateral triangle = 14 cm.

To find :

The area of equilateral traingle =?

Formula Used :

Area of equilateral traingle = (√3/4)a²

As We know that,

Area of equilateral traingle = (√3/4)a²

Substituting the values in the above formula, we get,

= (√3/4)(14)²

= (√3/4)14 × 14

= (√3/4) × 196

= √3 × 49

= 49√3

Therefore, Area of equilateral traingle = 49√3 cm².

Hence,

49√3 cm² is the correct option.
