Question

There are 640 acres in a square mile, 5280 ft in one mile, and 3.28 ft in one meter. How many acres are there in a hectare, which is a square one hundred meters on each side?

Answer 1

A hectare is 10,000 square meters, and since 1 acre is equal to 4.05 × 10³ square meters, there are approximately 2.47 acres in one hectare.

Step-by-step explanation:

To calculate the number of acres in a hectare, we first need to know the area covered by a hectare. A hectare is a square with 100 meters on each side. Using the conversion factors provided:

• A hectare is 100 meters × 100 meters = 10,000 square meters.
• 1 acre is equal to 4.05 × 10³ square meters.
• To convert from square meters to acres, we divide the area in square meters by the area of one acre in square meters:

10,000 m² / 4.05 × 10³ m²/ac = 2.47 acres

Therefore, there are approximately 2.47 acres in one hectare.
