Well, if given the perimeter of an equilateral triangle, you can find the lengths of the sides by using the formula \[S_{\text{Triangle}} = \frac{P}{3}\] dw:1357829776184:dw Afterwards, you'll have to draw the altitude which divides the base of the triangle in half. dw:1357829954412:dw Furthermore, you'd have to use Pythagorean Theorem to find the the length of the altitude

dw:1357830348662:dw so, how would i make this into a pythagoream theorom?

Split the bigger triangle into two smaller ones. Then just solve for one of the missing sides. The missing side is the altitude of course.

i got a=24.6 .. is that right?

c = 22 is the hypotenuse, right? So either leg has to be less than that. In other words a < c

So there's no way that a = 24. 6

11x11=121 and 22x22=484, then i added them together and 605 and the squareroot of 605 was 24.6 :c

a^2 + 11^2 = 22^2 a^2 = 22^2  11^2 a^2 = 484  121

a^2 + 11^2 = 22^2 a^2 = 22^2  11^2 a^2 = 484  121 a^2 =121(4  1) a^2 = 121(3) a = sqrt(121*3) a = sqrt(11^2)sqrt(3) a = 11sqrt(3)
