A labor is a historical unit of area used primarily in Texas and equates to 25 acres. To convert this area into square varas, it is essential to understand the relationship between acres and square varas.

One acre is equivalent to 43,560 square feet. A vara is a traditional unit of measurement that is roughly equivalent to 33.333 inches or about 2.78 feet. Therefore, when calculating the area in square varas for one labor (which is 25 acres), you would perform the following calculation:

1 acre = 43,560 square feet

25 acres = 1,089,000 square feet

Next, converting square feet to square varas involves the following steps:

1 vara² = (2.78 ft)² = 7.7284 square feet

To find the total square varas in 1,089,000 square feet:

1,089,000 square feet ÷ 7.7284 square feet/square vara ≈ 140,655 square varas.

If you would then relate this back to the options provided, the choice indicating 1,000 square varas would not reflect this conversion accurately. The correct kilovara measurement is far higher,
