Question

The height of an equilateral triangle is is 6 cm find its area how we will found it area

Answer 1

Answer:

12*sq.root(3) sq.cm

Step-by-step explanation:

In an equilateral triangle,

Height h=[sq.root(3)/2]*a

where a is side of the equilateral triangle.

Given h=6 cm,

Therefore a=12/(sq.root(3))

=> a=4*sq.root(3)

Area of equilateral triangle =1/2*a*h

=(1/2)*4(sq.root(3))*6

=12*sq.root(3) sq.cm.
