To find the parameter you have to add the length and the width and multiply by two
And your example long is the length and wide is the width so add it and times two answer is seven
Because the semi circle is too which is what it's inside but the answer is still seven
The given equation is 
By solving the given equation, we get


While solving the equation,we get 0=0.
Therefore, the given equation is true for all the values of y.
Hence, we can say that the given equation has infinite number of solutions.
