Question

23см2 + 118м2 + 9,3 м2 + 0,89см2

Answer 1

23 см² + 118 м² + 9,3 м² + 0,89 см² = 23 см² + 1180000 см² + 93000 см² + 0,89 см² = 1273023,89 см² = 127,302389 м²

Answer 2

To add the given areas together, you need to convert all the measurements to the same unit. Let's convert everything to square centimeters (cm²), since it's the smallest unit provided:

1 m² = 10000 cm² (1 square meter is equal to 10,000 square centimeters)

So, the expression becomes:

23 cm² + 118 m² + 9.3 m² + 0.89 cm²

Now, let's convert the areas:

118 m² = 118 * 10000 cm² = 1,180,000 cm² 9.3 m² = 9.3 * 10000 cm² = 93,000 cm²

Now the expression becomes:

23 cm² + 1,180,000 cm² + 93,000 cm² + 0.89 cm²

Now, add all the areas together:

23 cm² + 1,180,000 cm² + 93,000 cm² + 0.89 cm² = 1,273,023.89 cm²

So, the sum of the areas is 1,273,023.89 square centimeters.
