In any rectangle, the area is given by the product of the width and the length.
Since in this case both dimensions are represented by the correspondent function, you need to multiply the function:
First, let's use the Distributive Property to make our equation easier to solve. Remember that the Distributive Property says the following:
Using this, we can multiply the 7 out to the and 3. This gives us:
Now, let's solve for :
We can see that there is one solution for this equation because is equal to one definite value after solving. Thus, our answer is A, one solution.
