Question 1112156

Apothem of a regular triangle is   {{{ (s*sqrt(3)/6) }}}  where s is the length of each side.

Apothem = {{{ 17*sqrt(3)/6 = 4.9075 }}}  units.

===
Area = {{{ sqrt(3)/4 * s^2 }}}   where s is the length of each side

You can calculate it to find  it is 125.14 sq units.

Using the apothem to find the area:
—————————————————

The apothem can also be used to find the area:   Area = {{{ (1/2)*ap }}}   where a=apothem, p=perimeter

Area = {{{ (1/2)*4.9075*(3*17) = 125.14  }}} sq units
