28,672 feet squared. The area of a rectangle is it's length multiplied by its width, so you would multiple 512 with 56 to get your answer of 28,672. hope this helps :)
The answer would be C. 72
Hey there!
You are trying to find the perimeter of triangle ABC. Each side is 2. Since there are 3 sides on a triangle, multiply 2 by 3 to get 6. You do not need the centroid for this problem.
I hope this helps!
