Hey Mate!!
Area of equilateral ∆ =
Area of ∆ = 1/2 × base × height
=> 64√3 = 1/2 × 16 × h
=> 64√3 = 8h
=> 64√3 ÷ 8 = h
=> h = 8√3 cm
Hope it helps...✌️✌️

Step-by-step explanation:
We know that the altitude of equilateral triangle cuts it's base in two equal parts.
So ∆ABC if altitude is AD and cuts AC into AD and DC in 8cm.
Now, In ∆ABD, angle D = 90°
