A multiplication is zero if and only if at least one of the factors is zero. So, in this case, the multipications equals zero when

The first equation has no real solutions, because
is a square, and thus it's positive. If you add 4 to a positive number, the result can't be zero.
The second equation has the solution

So, globally, the expression equals zero if and only if 
Answer:
0 solutions
Step-by-step explanation:
These system of equations are inconsistent (parallel to each other) which means that there are no solutions to this system.
It would be better if you put a picture next time but i’ll just cauclate a normal rectangle to get the normal answer which is C) 196 square ft
