Area of an equilateral triangle of side ‘a’ units can be calculated by using the formula:
(a) √(s² (s-a)²)
(b) (s – a) √(s² (s-a))
(c) √(s (s-a)²)
(d) (s – a) √(s(s-a))

Answer:
the answer is option d
Step-by-step explanation:
When the sides of triangle are given we solve the area of the triangle using Heron's Formula which is
area of a triangle =Δ =
s(s−a)(s−b)(s−c)
where s is the semi-perimeter which equals s=
2
(a+b+c)
Here a=b=c , the formula gives us (s−a)
s(s−a)
