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.

Answer:
True.
Explanation:
Inflation is an economic term that can be defined as the increase in the prices of a product on the market in a given period.
It can occur due to several factors, when there is an imbalance between supply and demand, then it is correct to say that when the demand for a product is greater than the supply, there will be an increase in prices and, consequently, inflation.
It can also occur when there are situations of monopoly, which is the pricing of a product controlled by a company.
Another factor that causes inflation is the increase in a company's production costs, which can be caused by factors such as scarcity, or economic crisis.
Uncontrolled inflation has a negative impact on the consumer's life, which starts to lose its purchasing capacity and has its quality of life reduced.
