That would be 68.87 acres.
0.32 acres = 13,939.2 sq feet.
It is not entirely clear what the question is asking but the areas can be configured as80000 sq ft = 400 * 200 sq ft leaving an area of 400 * 200 sq ft, then 40000 sq ft = 400 * 100 sq ft leaving an area of 400 * 100 sq ft, then 10000 sq ft = 100 * 100 sq ft leaving an area of 300 * 100 sq ft, then 5000 sq ft = 100 * 50 sq ft leaving an area of 250 * 100 sq ft.
One acre has 43,560 square feet. Divide the number of square feet by that and you get the number of acres. This gives you an answer of .748 acres.
Answer: 14,400 ft² = 0.330578 acre
1 acre = 43,560 sq ft; 100 x 200 = 20,000 sq ft or .459 acre
200 ft * 200 ft = 40000 sq ft = 0.92 acres (approx)
200 ft * 900 ft = 4.13 acres (to 2 dp).
To convert feet to acres, you must first convert the dimensions to acres. One acre is equal to 43,560 square feet. Therefore, the area of 200 ft by 300 ft is 60,000 square feet. To convert this to acres, divide by 43,560, resulting in approximately 1.38 acres.
0.6565... (repeating) acres.
Answer: 20,000 ft² = 0.459136 acre
Answer: 60,000 ft² = 1.37741 acres.
Answer: 100 acres = 4,356,000 ft²
an acre is the area of about 200 ft X 200 ft (or 40,000 sq. ft.) so to answer your question regarding the 100 FT..., you must give a second dimension. For example: 100 Ft X ??? ft. hope this helped you.
About 2.06 acres for 100' x 900'
100 ft * 119 ft = 11900 sq ft = 0.273 acres
Answer: 100 acres = 4,356,000 ft²
