3М2 76дм2 98см2+9м2 58дм 2 43см2=??????

Answer 1

3 м2 76 дм2 98 см2 + 9 м2 58 дм2 243 см2 = (30000 см2 + 7600 см2 + 98 см2) + (90000 см2 + 5800 см2 + 243 см2) = 37698 см2 + 96043 см2 = 133741 см2 = 100000 см2 + 30000 см2 + 3000 см2 + 700 см2 + 41 см2 = 10 м2 + 3 м2 + 30 дм2 + 7 дм2 + 41 см2 = 13 м2 37 дм2 41 см2

Как то так...

Answer 2

To add these areas together, you need to sum the square meters (m²), square decimeters (dm²), and square centimeters (cm²) separately.

Let's start by adding the square meters:

3 m² + 9 m² = 12 m²

Next, add the square decimeters:

76 dm² + 58 dm² = 134 dm²

Finally, add the square centimeters:

98 cm² + 43 cm² = 141 cm²

Now, you have the sums for each unit:

12 m² 134 dm² 141 cm²

However, it's best to convert the square decimeters and square centimeters into square meters to get a single unit for the total area:

1 dm² = 0.01 m² 1 cm² = 0.0001 m²

So, for the square decimeters and square centimeters:

134 dm² = 134 * 0.01 m² = 1.34 m² 141 cm² = 141 * 0.0001 m² = 0.0141 m²

Now, add all the areas in square meters:

12 m² + 1.34 m² + 0.0141 m² = 13.3541 m²

So, the total area is 13.3541 square meters.
