Answer 2

Answer:

area of an equilateral triangle is 0.048 (unit)²

Step-by-step explanation:

given that :

the perimeter of an equilateral triangle is 1 unit;

we know the formula for solving perimeter of equilateral triangle :

the perimeter of an equilateral triangle = 3a

where a can be assumed as side length of equilateral triangle

let us equate given value of the perimeter of an equilateral triangle as:

3a = 1 unit

so , a = (1/3) unit

area of an equilateral triangle is $(\sqrt{(3)} /4 )a^2$

area is $\sqrt{3}$/4 X (1/3)²

area is ($\sqrt{3}$/4 ) (1/9)

area of an equilateral triangle  is $\sqrt{3}$/36 = 1.732/36 = 0.048 (unit)²
