You must not want help for this problem since you have ignored the answer you've already received.

You do not say what the question is. When Steve answered he guessed you wanted the area of the triangle, and that seems a reasonable assumption. However you posted this question twice with no question.

sorry guys i ended up pressing submit on accident. the question was asking to write a formula for the area of an equilateral triangle in terms of the following: Write a formula for the area of an equilateral triangle in terms of the following:
A.in terms of the length of a side,s, only
B. in terms of the height, h only.
I am having a hard time with this question, as I recall is the area for a triangle when only given side and height is sh/2?

from right triangle of hypotenuse s and leg s/2 you get
h = (s/2)sqrt 3 so s/2 = h/sqrt3
then
area = A = (s/2)(s/2)sqrt 3 = (s^2/4)sqrt 3
and A = (s/2)h = (h/sqrt 3)h =h^2 /sqrt 3
h = (s/2)sqrt 3 so s/2 = h/sqrt3
then
area = A = (s/2)(s/2)sqrt 3 = (s^2/4)sqrt 3
and A = (s/2)h = (h/sqrt 3)h =h^2 /sqrt 3
