Question 96231: Help again! It seems there are different ways to figure out problems for rectangles, squares, and triangles. Is there a different formula for all of them. The questions I'm working with give me the perimeter I have to figure out the dimensions. I FEEL SO OVERWHELMED!

ex. A square has a perimeter of 28 feet. Find the length of each side.

ex. A triangle has a perimeter of 23 inches. The medium side is 3 inches more than the shortest side, and the longest side is twice the shortest side. Find the shortest side.
