Question 347798: A field has a rectangular shape. If the area is 5 square meters and the perimeter is 24 meters how far is it from one corner to the opposite corner?
I tried making a list of lengths and widths to get a perimeter of 24 but then the area was never 5 and if I found sides with an area of 5 the perimeter was no longer 24. I know I need to use the pythagorean theorem to find the diagonal but I don't know how to find the sides first.
Thanks.
