Question

The area of an equilateral triangle is 16 root3 m^2. Find its perimeter (in meters).

Answer 1

The Area of the Equilateral Triangle is √3/4×side of the Triangle=√3/4×s
Area=16√3 (metre)²
16√3=√3/4×s
⇒√3s=16√3×4
⇒s=64√3/√3
⇒side=64 metres
Now the Perimeter of the Equilateral triangle P=3×Side
P=3×64
⇒Perimeter = 192 m                                   Ans.
