If three rectangles have the same area, does it mean they will also have the same perimeter? Prove it on the board!!
Just because three rectangles have the same area, it doesn't always mean they will have the same perimeters.
If two rectangles have the same perimeter, does it mean they will also have the same area? Prove it on the board!
No, just because two rectangles have the same perimeter does not always mean they will have the same area.
