Answer:
The answer is below
Step-by-step explanation:
9) The area of the platform = length * width = 9 m * 12 m = 108 m²
Area = 108 m²
11) 1 km² = 1 km × 1 km = 1000 m × 1000 m = 1000000 m²
But 1 hectare = 10000 m², hence:
1000000 m² = 1000000 m² / 10000 m² per hectare = 100 hectares
1 km² = 100 hectares
12) Area of each paper = 16 cm * 12 cm = 192 cm²
There are 48 sheets, hence:
Total area of sheets = 192 cm² * 48 = 9216 cm²
13) Area of each tile = 12 cm * 10 cm = 120 cm²
The kitchen contains 500 tiles, therefore:
Area of kitchen = 120 cm² * 500 tiles = 60000 cm²
1 m² = 10000 cm²
60000 cm² = 60000 cm² / 10000 cm² per m² = 6 m²
Area of kitchen = 6 m²
