use the Pythagoras theorem method
a squared plus b squared equals c square
Area = πr^2
π4^2 =16π

Given:
LMN is an equilateral triangle.
LM = LN = MN = 12 cm
To find:
The height of the triangle h.
Solution:
In a right angle triangle,



Multiply both sides by 12.


Therefore, the height of the triangle is
cm.
