12 m is the answer bro bro

Answer 2

Answer:

12

• The way how to get the answer is given below:

Step-by-step explanation:

As we know the area of an equaleteral triangle is √3/4 a², where 'a²' is the length of the side.

So here lets give the value for 'a²' and check one by one options given in the paper and check if we are getting 36√3.

If we are getting 36√3, then that value of 'a' is the right answer.

So, lets give 12m for 'a'

then,

√3/4 x (12)²

= √3/4 x 144

*(we can cancel 4 and 144, then we will get:)

√3/2 x 72

*(Now too we can cancel 2 and 72 as they have common factors)

then we will get,

√3 x 36

that is 36√3, which is same as the question.

• So therefore, the answer is 12m.
