Algebra.Com's Answer #330255 by kingme18(98)![]() ![]() You can put this solution on YOUR website! Equilateral means all sides are equal. A triangle has 3 sides. An equilateral triangle has 3 equal sides, each of which has a length of 18 for this problem. Since perimeter means to add the lengths of the sides, we'll add 18 + 18 + 18 = 54. \n" ); document.write( " |
