Jones has a 100-acre farm. he sells it to a developer who is going to build houses. the developer will use 10% of the land for s
Sholpan [36]
The first thing we must do is find the amount of land that will be used for the 120 lots.
 We must remember that 10% of the land will not be used for the lots.
 We have then:
 100 - (0.10) * (100) = 100 - 10 = 90 acres.

 Then, we must consider the following conversion of units:
 1 acre = 43560 ft ^ 2

 Applying the conversion we have:
 (90) * (43560) = 3920400 ft ^ 2

 Then, the amount of square feet for each lot is given by:
 3920400/120 = 32670 ft ^ 2

 Answer:
 
There will be 32670 square feet in each lot.
