Your lawn is 8 m × 6 m. Grass seed costs $2.50 per square metre. What's the bill?
Try this
48
cost = area × $2.50/m², plus 10% for waste = $120.00 for seed → $132.00 including 10% extra for edges & waste
Area first, then money
Find the lawn's area (length × width for a rectangle), multiply by the price per square metre, then pad it. Most landscapers add about 10% for overlaps, awkward edges and bare patches that need a second pass.
Your turn
A lawn is 12 m × 5 m and seed costs $2.50 per m². What's the bill before any waste allowance?
For an L-shaped or irregular lawn, chop it into rectangles, find each area, and add them up before multiplying by the price.
Try it
Total cost
Area = 8 × 6 = 48 m². Cost = 48 × $2.50 = $120.
Always add 10% for waste and edges. Real-world quotes always have a fudge factor.
