Answer:
The correct answer is A.
Step-by-step explanation:
The area of a rectangle can be calculated using the following formula:
If we know that the area measures and one side of the figure measures 4.2 m, we can say that:
We isolate the side we don't know:
So I = 9 m
To know the perimter of a rectangle, we use the following formula:
The zero product property tells us that if the product of two or more factors is zero, then each one of these factors CAN be zero.
For more context let's look at the first equation in the problem that we can apply this to:
Through zero property we know that the factor
can be equal to zero as well as 
. This is because, even if only one of them is zero, the product will immediately be zero.
The zero product property is best applied to factorable quadratic equations in this case.
Another factorable equation would be
since we can factor out 
and end up with 
. Now we'll end up with two factors, and 
, which we can apply the zero product property to.
The rest of the options are not factorable thus the zero product property won't apply to them.
