A rectangular field has a length of 120 meters and a width of 80 meters. A path of uniform width is built around it, expanding the total area to 13,000 square meters. What is the width of the path? This question reflects growing interest in spatial design, sustainable landscaping, and functional outdoor spaces—trends amplified by rising home renovation engagement and smart land use in the U.S. Many homeowners and planners are reimagining traditional yards to balance aesthetics with practicality, especially in suburban settings where outdoor areas often define lifestyle value.
A rectangular field has a length of 120 meters and a width of 80 meters. A path of uniform width is built around it, expanding the total area to 13,000 square meters. What is the width of the path? This question reflects growing interest in spatial design, sustainable landscaping, and functional outdoor spaces—trends amplified by rising home renovation engagement and smart land use in the U.S. Many homeowners and planners are reimagining traditional yards to balance aesthetics with practicality, especially in suburban settings where outdoor areas often define lifestyle value.
A rectangular field with dimensions 120m × 80m covers 9,600 square meters. When a uniform-footpath surrounds the field, it adds consistent border space, increasing total area to 13,000 square meters—an expansion of 1,400 square meters. This precise geometry makes the problem both accessible for calculation and relevant to real-life design challenges facing U.S. property owners today.
The field’s original area is 120 × 80 = 9,600 m². The expanded area with path adds 1,400 m², forming a new rectangle with outer dimensions based on uniform widths on each side. If the path width is x meters, then the total length becomes (120 + 2x) and width becomes (80 + 2x). Multiplying these gives:
(120 + 2x)(80 + 2x) = 13,000
Expanding:
9,600 + 400x + 4x² = 13,000
Simplifying:
4x² + 400x – 3,400 = 0
Dividing through by 4:
x² + 100x – 850 = 0
Understanding the Context
This quadratic equation models the true challenge behind measuring and optimizing outdoor space, showing how small uniform expansions can yield substantial changes. Solving this gives x ≈ 6 meters—an outward expansion safe enough in most residential contexts but meaningful in area impact.
Why is this field-path calculation gaining traction now? Mobile-first users, especially in housing-obsessed regions like the American South and Midwest, seek data-driven insight on improving yards without costly overhauls. The formula combines design intuition with arithmetic precision—ideal for the Discover audience searching “how to calculate large outdoor spaces” or “rectangular plot with border.”
Understanding the path’s width supports informed decisions about irrigation zones, planting beds, or accessible walkways, all critical for functional outdoor landscapes. The 6-meter width maintains space efficiency while aligning with typical DIY landscaping feasibility—not too wide for proportion, yet wide enough for usability.
仍有常见误解：一些 Nutzer假设更宽路径更安全或美观，但实际增加宽度会 squeeze usable space. Pure math confirms a 6-meter path preserves optimal balance between border and inner field, ideal for recreation, gardening, or gathering.
