To find :-

• Area of the equilateral triangle.

Step by step explanation :-

Detailed explanation of solution :-

Let's understand!

In the question, Given that, The length of a equilateral triangle is 12cm.

We are asked to find area of that triangle.

How to solve ?

We will use this formula to find the area of an equilateral triangle ➝ √3/4 S².

Here, S = 12cm.

Let's do it!

Calculations :-

Area of ∆ = √$\sf \frac{3}{4}$ × 12 × 12

➜ √3 × 3 × 12

➜ √3 × 36

➜ 36√3 or 62.35

Therefore, The area of the equilateral triangle is 36√3.
