A rectangular garden is 20 meters long and 15 meters wide. A path of uniform width is built around the garden, increasing the total area to 546 square meters. What is the width of the path? - Treasure Valley Movers

How a 20-Meter by 15-Meter Garden with a Uniform Path Expands to 546 Square Meters — The Width You’re Looking For

If you’ve ever wondered how a simple rectangular garden transforms when surrounded by a steady, uniform path, you’re not alone. This common landscaping design sparks interest because it balances practicality and aesthetics — a narrow walkway not only frames the garden but invites intentional space use. Recently, curiosity about this setup has surged, especially as homeowners and community planners seek sustainable, attractive yard enhancements without overspending. The question stands clear: What uniform width should the path have to double the total area to 546 square meters? This isn’t just a math puzzle — it’s a design challenge reflecting broader trends toward eco-conscious outdoor living in the U.S.

A rectangular garden measuring 20 meters by 15 meters introduces a baseline footprint of 300 square meters. When a path of uniform width surrounds this rectangle, it adds to both length and width equally. The challenge lies in calculating that precise width so the total area reaches exactly 546 square meters, merging function with form in a space optimized for relaxation, growth, or outdoor living.

Why This Configuration Is Gaining Traction

The combination of a well-proportioned garden and a uniformly wrapped path reflects a growing interest in smart, walkable outdoor spaces in American communities. As more households seek to create functional yet inviting yards, this design pattern aligns with modern preferences for landscaped zones that support privacy, community gatherings, and low-maintenance greenery. The rectangular shape, simple symmetry, and predictable expansion make it ideal for both single-family homes and intentional backyard retreats. Meanwhile, the total area of 546 square meters offers just enough room for a modestly sized vegetable bed, flower borders, or seating areas — enough space to enhance quality of life without overwhelming small to mid-sized gardens.

The shift toward sustainable, low-input landscape design has elevated attention on this type of garden layout. Using a uniform path ensures even weight distribution and easier maintenance, reducing soil compaction and simplifying seasonal care. It also supports the trend of integrating edible and ornamental plants close to where they’ll be enjoyed — enhancing both beauty and usability.

How Does the Path Width Affect the Total Area?

To understand the path’s measurement, imagine extending the original garden by x meters on each side. This widens both length and width to:

• Length: 20 + 2x
• Width: 15 + 2x

Total area then becomes:
(20 + 2x)(15 + 2x) = 546

Expanding this equation:
300 + 70*x + 4x² = 546
4x² + 70x – 246 = 0

Solving this quadratic confirms the path width that transforms 300 m² into 546 m² is approximately 1.4 meters — a width wide enough to be noticeable yet narrow enough to preserve garden intimacy and ease of navigation.
