2170м

2)26км722м/62+35м=26722м/62+35м=

431м+35м=466м

Answer 2

To solve this expression, follow the order of operations (PEMDAS/BODMAS: Parentheses/Brackets, Exponents/Orders, Multiplication, and Division, from left to right, Addition, and Subtraction).

Let's break down the expression step-by-step:

1. Perform the division: 30km 814m ÷ 71 and 526km 722m ÷ 62.

   • (30km 814m ÷ 71) ≈ 0.433 km (approximately)
   • (526km 722m ÷ 62) ≈ 8.499 km (approximately)

2. Perform the multiplication: 0.433 km × 8.499 km ≈ 3.678 km^2 (approximately)

3. Add the remaining term: 3.678 km^2 + 35m

Since the units are different (km^2 and meters), we need to convert them to the same unit before adding:

1 km = 1000 m, so 3.678 km^2 = 3.678 × (1000 m)^2 = 3,678,000 m^2

Now add: 3,678,000 m^2 + 35 m = 3,678,035 m^2

Therefore, the final result is approximately 3,678,035 square meters.
