Area of the equilateral triangle - 3 * side24 = √3 * 42 4 = 4√3 = 6.92820....

Area of the scalene triangle (by Heron's formula)
= √s(s-a)(s-b)(d-c) where s= semiperimeter = (a+b+c)/2 and a, b, c are the three sides
Therefore, area = √6*3*2*1 = √36 = 6
However, this triangle is a right triangle. So, you can solve it by the formula (Base * Altitude)/2 where Base = 3 or 4 and Altitude = 4 or 3. In all the cases, the answer is same.

So, Area of Equilateral Triangle > Area of Scalene Triangle.
