Question

Find the length of an equilateral triangle of area 10.2 m^2​

Answer 1

Answer:

It's simple just see.

Step-by-step explanation:

Area Of Equilateral Triangle is

A= (√3/4)xa^2

Given that ,

Area Of Equilateral Triangle is 10.2 m^2

Now, (√3/4)xa^2 = 10.2

or, a^2 = 10.2 x  (4/√3)

or, a^2 = 68√3/5

or, a = √(68√3/5)

So, a = 4.85

The length of the equilateral triangle is 4.85
