You can't as there is no hypotenuse in an equilateral triangle. The hypotenuse is the side of a triangle which is opposite a right angle (90°); all angles in an equilateral triangle are 60°.
If the triangle is equilateral, you simply divide the perimeter by three to find the length of each side. If the triangle is not equilateral, you will need more information to determine the length of each side.

If a triangle is isosceles, then it is equilateral. To find the converse of a conditional, you switch the antecedent ("If ____ ...") and consequent ("... then ____."). (Of course, if not ALL isosceles triangles were equilateral, then the converse would be false.)
Altitude = 10.4 (10.3923) cm
5.7735 cm is the length of a side so 1/2 x base x Height should give you an answer. Remember, the apothem makes two mirrored 30 60 right triangles...Pythagoras will tell you how to find the hypotenuse...that will be the unknown side of the equilateral.

It is called and equilateral triangle. You can find more information about equilateral polygons here: http://www.answers.com/equilateral
Use Pythagoras' theorem to find the triangle's altitude or height: 122-62 = 108 and the square root of this is 10.39230485 1/2*base*height = area 1/2*6*10.39230485 = 31.17691455 square units
A regular pentagon has five (5) equilateral triangles within it. Find the area of each triangle (1/2bh where b is the base of the triangle or the length of a side of the pentagon, and h is the height of the triangle or the apothem of the pentagon) and multiply the area of the triangle times five (5).
An equilateral triangle has 3 lines of symmetry which perpendicularly bisects each of its vertices
Find the area of an equilateral triangle if its perimeter is 18 ft
3.5
If the triangle is equilateral, you simply divide the perimeter by three to find the length of each side. If the triangle is not equilateral, you will need more information to determine the length of each side.
