Question

In an equilateral triangle with side 24cm then find the length of altitude

Answer 1

Answer: 20.78

Step-by-step explanation:

Area of ∆ = ½*b*h

& Area of equi∆ = √3/4.a² =249.42

249.42=½*24*h

249.42=12*h

h=20.78

Answer 2

Length of Altitude of equilateral triangle is

√3/2(side)

√3/2(24)

24√3/2

=12√3
