Question

What is the height of the equilateral triangle which has the side as 8cm?​

Answer 1

Answer:

height = 4√3 cm.

Step-by-step explanation:

Side = 8cm

Thus, area of equilateral ∆ = (√3a^2)/4

= √3(64)/4

= 16√3

Let height of equilateral ∆ = h

Thus, Area = 1/2(a)(h)

16√3 = 1/2(8)h

h = 4√3 cm.

Answer 2

Altitude of an equilateral triangle is given by

√3a/2.

Thus, Height of this equilateral triangle = √3(8)/2

= 4√3
