Question 1180920

The height of an equilateral triangle is 15cm and its base is 36cm find the area of the triangle

In general, the height of an equilateral triangle is equal to {{{sqrt(3)/2}}} times a side of the equilateral triangle. =>{{{h=(sqrt(3)/2)s}}}
The area of an equilateral triangle is equal to 


{{{A=(1/2 )* ((sqrt(3)/2)s )* s }}}

{{{A= (sqrt(3)*s^2)/4}}}



given:
{{{h= 15cm}}}
{{{b= 36cm}}}

{{{A= (sqrt(3)*36^2)/4}}}

{{{A= 2244.737846609265/4}}}

{{{A=561.18cm^2}}}
