A rectangular garden measures 30 meters by 20 meters. A path 2 meters wide runs along the inside perimeter, creating a walkway that reduces usable planting space while defining the garden’s border. This design is gaining attention among US homeowners seeking functional outdoor layouts that balance aesthetics and utility. The narrow 2-meter path cuts deeply into the garden’s footprint, and calculating its area isn’t just a math exercise—it reveals how thoughtful planning shapes real-world garden spaces. What exactly is the area taken by the path? Understanding this helps optimize both design choices and expectations. A rectangular garden measuring 30 meters by 20 meters forms a rectangle with an internal space enclosed by a perimeter fence or border. Adding a 2-meter-wide path inside the garden’s edge leaves narrower planting zones, especially near corners. The full rectangular footprint includes the outer dimensions, but the usable planting area shrinks inward by 4 meters on each side—2 meters on every interior side—due to the path’s consistent width. Calculating just the ground area removed by the path uncovers a precise measurement rooted in geometry, offering clarity for garden planning. To determine the path’s area, begin with the full garden’s area: 30 meters times 20 meters equals 600 square meters. The path runs along the inside perimeter, so the remaining planting zone forms a smaller, inner rectangle. The inner rectangle’s dimensions shrink uniformly by 4 meters—2 meters subtracted from each edge (2 meters on the length and 2 meters on the width). This results in a planting area of (30 – 4) by (20 – 4), or 26 meters by 16 meters, which equals 416 square meters. Subtracting the usable planting area from the total area reveals the path’s area: 600 – 416 equals 184 square meters. This 184 square meter path daily interacts with outdoor lifestyle trends—from gardening enthusiasts seeking efficient space use, to homeowners valuing walkable, structured garden designs. The inner planting area’s reduction of 184 sq m influences scheduling planting, soil quality, and maintenance—but the math remains precise within consistent, real-world measurements.
