Answer:

Right .

Step-by-step explanation:

Let the sides of triangle is a

in ∆ABC AD perpendicular to BC

AB² = AD² + BD²

4a² -a² = AD²

√3 a = AD

Area of ∆ ADB = 1/2 × b × h

= 1/2 × a × √3 a

= √3 a²/ 2

Area of ∆ ABC = s = a +b+c/2

2a +2a +2a / 2

= 3a

Herons formula = √ s(s-a)(s-b)(s-c)

√ 3a( a)(a)(a)

√3 a²
