The number of possibilities that are there for the ordered pair is 2.
<h3>Calculation and Parameters
</h3>
Because the unpainted part of the floor covers 1/2 of the area, then the painted rectangle covers 1/2 of the area as well.
Given that the border width is 1 foot, the dimensions of the rectangle are a-2 by b-2.
Making an equation:
ab= 2((a-2)(b-2))
ab= 2ab-4a-4b+8
ab-4a-4b+8=0
If we apply Simon's Favorite Factoring Trick,
ab-4a-4b+16= 8
(a-4)(b-4)= 8
Since b > a, then we have the possibilities
(a-4) = 1 and (b-4) = 8, or (a-4) = 2 and (b-4) = 4.
(5, 12) or (6,8) which gives us 2 possibilities.

template is otherwise called the four-column bank reconciliation.
