Solution

The image shows two rows with dimensions and areas in different units. Let's solve the problem for each row.

Row 4:

  • Dimensions: 6 cm and 12 dm
  • Area: 96 dm²

First, convert the dimensions to the same unit:

  • Convert 6 cm to decimeters (dm): 6cm=0.6dm6 \, \text{cm} = 0.6 \, \text{dm}

Now, calculate the area using the formula: Area=length×width\text{Area} = \text{length} \times \text{width} Area=0.6dm×12dm=7.2dm2\text{Area} = 0.6 \, \text{dm} \times 12 \, \text{dm} = 7.2 \, \text{dm}^2

However, this calculated area (7.2 dm²) does not match the given area of 96 dm². This discrepancy suggests that the area provided might be related to something else, such as the result of another dimension or scale factor. To resolve the issue properly, a further step is needed, or there might be a mistake in the original table.

Row 5:

  • Dimensions: 8 m and 7 m
  • Area: 168 m²

Calculate the area using the formula: Area=length×width\text{Area} = \text{length} \times \text{width} Area=8m×7m=56m2\text{Area} = 8 \, \text{m} \times 7 \, \text{m} = 56 \, \text{m}^2

This calculated area (56 m²) also does not match the given area of 168 m², similar to the issue in Row 4. This discrepancy might indicate that the problem involves some additional scaling or misunderstanding of the area given.

Would you like to investigate further, or is there any other aspect of the problem you'd like to explore? Here are five related questions to consider:

  1. Could the area values given in the table be a result of multiplication involving a scale factor?
  2. How would the calculated area change if you used different units for the dimensions?
  3. What assumptions can you make to reconcile the differences between calculated and given areas?
  4. If the table involves scaled measurements, what might be the scale factor applied?
  5. Could there be any missing dimensions or values not listed in the table that affect the area calculation?

Tip: Always double-check the units when dealing with area calculations to ensure consistency across the dimensions.
