Perimeter: word problems
Perimeter tells you how far it is around a shape. It is perfect for borders, fences, and tracks.
Concept
Perimeter is the total length around the edges. For rectangles: **P = 2 Ć (length + width)** Example: A garden is 14 ft by 9 ft. P = 2 Ć (14 + 9) = 2 Ć 23 = 46 ft šļø Think like a field designer: - Want to put rope around a court? Use perimeter. - Want to run one lap around a track? Use perimeter. - Want to frame a poster? Use perimeter.
