Question

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 streets, sewers, and parks. he will divide the rest of the land into 120 lots. how many square feet will be in each lot?

Answer 1

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.
