Question

•The area of equilateral triangle whose height is 'h'.....​

Answer 1

Answer:

Step-by-step explanation:

Altitude of an equilateral triangle , bisects the base. If each side = a unit

By Pythagiras law, a² = (a/2)² + h²

=> a² - a²/4 = h²

=> h = √(3a²/4) = √3a/2

=> a = 2h/√3

Area( triangle) = 1/2 * a * h

=> area = 1/2 * 2h/√3 * h = h²/√3 = √3h² /3

Area = √3h² /3

Answer 2

Answer:

3h

Step-by-step explanation:

s+s+s = hight

h+h+h =3
