You just want to multiply 4 time the area of the figure, right? Sure, the area is 12 times the area of a single triangle. What's the area of an equilateral triangle with side 1? That's a trig problem, not a calc problem.

Thanks

Just to clarify:

So you're saying that we don't even need the integral because you can pull the 4 out and if you just integrate (1), you get 1/2?

Then I multiply by 12 so the answer is 4*12*(1/2)=24?
That's ok up until you integrated 1 over the triangle and got 1/2. The area of a triangle with side length 1 isn't 1/2, is it?

Thanks again!
