Answer 2

To solve this expression, let's break it down step by step:

1. Convert the measurements to a common unit (centimeters) and calculate the values:

• 7 meters 1 decimeter = (7 * 100 cm) + (1 * 10 cm) = 710 cm
• 8 * 2 * 8 = 128
• 8 + 8 + 8 = 24
• 9 meters 3 centimeters = (9 * 100 cm) + (3 cm) = 903 cm
• 3 meters 92 decimeters = (3 * 100 cm) + (92 * 10 cm) = 1290 cm
• 27 * 94 = 2538
• 2748
• 46 * 49 = 2254
• 462.5 * 5 * 2 = 4625

Now, let's rearrange the expression with these values:

(721 cm * 710 cm) + 128 + 24 - (903 cm * 1290 cm) - 2538 - 2748 + 2254 + 4625

2. Perform the multiplications and subtractions:

(512710 cm^2) + 128 + 24 - (1168770 cm^2) - 2538 - 2748 + 2254 + 4625

3. Now, let's calculate the differences:

(512710 cm^2) + 152 - (1168770 cm^2) - 2538 - 2748 + 2254 + 4625

4. Calculate the final result:

512710 cm^2 + 152 - 1168770 cm^2 - 2538 - 2748 + 2254 + 4625 = -656858 cm^2

So, the final result is -656,858 square centimeters.
