help me please​

Answer 1

Step-by-step explanation:

Let ABC is an equilateral ∆ in which AB=BC=CA= x(let) and height AD=10√3

units.

In right ∆ ADC , AD/AC = sin60°

(10√3)/x = √3/2 or x = 20units.

Area of equilateral ∆ = (√3/4)•side^2

=√3×400/4sq.units

=100√3 = 100×1.732 = 173.2 sq.units. Answer.
