okay to make the problem simpler ill just tell you what it is.
im supposed to find the perimeter and area of an equilateral triangle.
There is a mini right trangle on the bottom left side, the height of that triangle is the bottom of the equilateral, but not as long.
Since it is a right triangle, there is 30,60, and 90 degrees.
The base is 6 and the hypotenuse is 12
I used the formula 1/4 X S2 X the square root of 3. S= 6 in this case, so plugging it in it would be 1/4 X 36 X the square root of three.
i used a calculator and that averages out to 9 square root 3.
So that is the area, but I need to find the perimeter...how?
