Question from sheryl: a 50*70 horse pen is 240 feet and 3500 square feet why is there a 100 square feet difference? |
Hi Sheryl,
Look at the answer I gave to a similar question by Brooklyn. If you know then perimeter of a rectangle (the amount of fencing around your pen) then different shapes will give different areas. For example you could take the 240 feet of fencing and make the pen 4 feet wide and 116 feet long then the area is 4 × 116 = 464 square feet. Your rectangular pen has the largest area possible if it is a square.
