Answer 2

Answer

• The cost to polish will be ₹ 6300

Explanation

We are given that,

• A floral design has 280 tiles
• Each tile is shaped like a parallelogram
• Height = 3 cm
• Base = 5 cm

We have to find,

• Cost of polishing the design at ₹1.50 per m²

━━━━━━━━━━━━━━━━

Area of the parallelogram has been given by,

➝ Area of parallelogram = Base × Height

• Base = 5 cm
• Height = 3 cm

Substituting the values,

➝ Area = 5 × 3

➝ Area = 15 cm²

Then the area for 280 tiles will be,

➝ Total Area = Area × Number of tiles

➝ Total Area = 15 × 280

➝ Total Area = 4200 cm²

Then the final cost will be,

➝ Total Cost = Total Area × Cost per cm²

➝ Total Cost = 4200 × 1.50

➝ Total Cost = ₹6300
