I need someone that knows math to help me with this problem.

Since the house has 2 floors, and each floor has an area of:
[tex]31ft\times49ft=1519ft^2\text{.}[/tex]Therefore, the total area of the house is 1519ft²x2=3038ft². Since the average price per square foot is $107, then the current value of the house is:
[tex]3038\cdot107\text{ dollars=}325066\text{ dollars.}[/tex]Answer:
The footage of Jackson's home is:
3038 square feet.
The current fair market value of their house is:
$325066.
