Question

3 м2 9дм2=? ДМ2 6 ДМ2 20СМ2=?СМ2 2 м2=?СМ2 9 ДМ2=?ММ2

Answer 1

3м2 9дм2=309дм2

6дм2 20см2=620см2

2м2=20000см2

9дм2=90000мм2

Answer 2

1. 3 м² 9 дм² = (3 x 100 + 9) дм² = 309 дм²
2. 6 дм² 20 см² = (6 x 100 + 20) см² = 620 см²
3. 2 м² = 2 x 100 x 100 см² = 20,000 см²
4. 9 дм² = 9 x 100 см² = 9000 см² = 0.9 м²
5. To convert from dm² to mm², we need to multiply by 100, since 1 dm = 10 cm and 1 cm = 10 mm. So, 9 dm² = 9 x 100 x 100 mm² = 90,000 mm².
