Question

45 га = а =м2? 4 дм2= см2=мм2

Answer 1

45 га=4500 а = 450000 м2

4дм2=400см2=40000мм2

Answer 2

To convert between different units of area, we'll use the following conversion factors:

1 hectare (ha) = 10,000 square meters (m²) 1 decimeter (dm) = 100 square centimeters (cm²) 1 centimeter (cm) = 100 square millimeters (mm²)

Let's do the conversions step by step:

1. Converting 45 hectares to square meters: 1 ha = 10,000 m² 45 ha = 45 * 10,000 m² = 450,000 m²

So, 45 hectares is equal to 450,000 square meters.

2. Converting 4 square decimeters to square centimeters: 1 dm² = 100 cm² 4 dm² = 4 * 100 cm² = 400 cm²

So, 4 square decimeters is equal to 400 square centimeters.

3. Converting 400 square centimeters to square millimeters: 1 cm² = 100 mm² 400 cm² = 400 * 100 mm² = 40,000 mm²

So, 400 square centimeters is equal to 40,000 square millimeters.
