Problem 1: Find Missing Side
Naya’s carpet area is 84 sq ft and one side is 7 ft. What is the other side? Solution: Other side = 84 ÷ 7 = 12 ft. Sides: 7 ft and 12 ft.
Problem 2: Cut Into Largest Equal Squares
Carpet measures 18 ft by 30 ft. GCD(18,30) = 6 ft. Largest square size is 6×6 ft. Number of squares = (18×30)/(6×6) = 540/36 = 15 squares. Fifteen squares of 6 ft side with no waste.
Problem 3: Fit Small Rugs
From a 12 ft by 9 ft carpet, how many 3 ft by 2 ft rugs can be cut? Orientation A (3×2): floor(12/3)=4 across, floor(9/2)=4 down → 16 pieces. Orientation B (2×3): floor(12/2)=6 across, floor(9/3)=3 down → 18 pieces. Rotating the small rug yields 18 pieces (best option).
Algebraic And Quadratic Cases
Some problems require solving quadratic equations: for example, when a carpet is reduced or enlarged by a fixed margin or when parts are removed. Set up equations carefully and check both algebraic roots for physical feasibility (positive lengths).
Illustration: Add A Border
Naya adds a uniform border so the new perimeter increases by 16 ft. If original dimensions are L and W, and border width is x, then new perimeter P’ = 2(L + 2x + W + 2x) = 2(L + W + 4x). Given P’ − P = 16, solve for x as needed. Translate the physical change into algebraic terms to solve.
Optimization: Minimizing Waste When Cutting Multiple Sizes
When cutting a mix of sizes, use a cutting-stock approach: prioritize large pieces, then fill remaining areas with smaller pieces. Software tools and integer programming can yield optimal patterns when manual heuristics are insufficient. Start with a greedy largest-first cut, then iterate improvements locally.

Practical Installation And Care Tips
Beyond math, practical issues affect the carpet’s lifecycle. For installation, acclimate the carpet to room temperature, allow cushion and backing considerations, and plan seam placement away from high-traffic lines. For care, vacuum regularly, clean spills promptly, and rotate the carpet if wear patterns appear.
Common Mistakes And How To Avoid Them
Typical mistakes include ignoring units, forgetting seam and pattern allowances, and failing to test alternate orientations. Double-check units, add appropriate margins, and try both orientations for cutting and placement.
Resources And Tools For Carpet Calculations
Useful tools include online carpet calculators, GCD calculators for cutting, and floor-plan apps for placement visualization. For complex cutting or high-cost materials, consider consulting a professional installer or a cutting optimization service to minimize waste.
Frequently Asked Questions Related To Rectangular Carpet Problems
Q: How to compute the largest square from a carpet with non-integer dimensions? A: Use the greatest common divisor concept extended to rational numbers by scaling to integers, or compute the largest square side as the greatest common measure of the lengths; practical cutting will be limited by unit constraints. Q: Is diagonal fitting always possible? A: Not always; it requires checking the room opening and diagonal clearance carefully. Test with exact diagonal calculations before attempting to maneuver the carpet.
Final Notes On “Naya Had A Rectangular Carpet” Scenarios
Problems introduced by the phrase “Naya Had A Rectangular Carpet” are versatile and map to algebra, number theory (GCD), optimization, and real-world installation planning. Applying the core formulas, considering practical allowances, and testing alternate orientations solve most typical questions efficiently.
