find its perimeter.(ii) If the area of an equilateral triangle is 8/3

1.	find its perimeter.(ii) If the area of an equilateral triangle is 8/3 cm,find its height.
Answer» First of all let us calculate the side of this equilateral triangle. Let the sides of equilateral triangle be "s" cm. Also, Area of equilateral triangle = √3/4×(s)² Then, √3/4 × (s)² = 8√3 => => s =√32m. Now, by using the formula, we get : Height of equilateral triangle = √3/2 × √32 = = cm.

Answer»

First of all let us calculate the side of this equilateral triangle.

Let the sides of equilateral triangle be "s" cm.

Also, Area of equilateral triangle = √3/4×(s)²

Then, √3/4 × (s)² = 8√3

=> => s =√32m.

Now, by using the formula, we get :

Height of equilateral triangle

= √3/2 × √32

= cm.
