If you were to have (3,2) and find the reflection of the y axis, it would turn y into a negative, making it (3,-2).
check the picture below.
so, we know the radius of this circle is 5 then, namely, the distance from (0,0) to (5,0) is 5.
now, if (√(21) , 2) indeed lies on that circle curve, then the distance from (0,0) to (√(21) , 2) will also be the same radius of 5 units.

I believe the answer you're looking for is A. Commodity money
Hope this helps!

Given
The area of a rectangle is 
The length of the rectangle is 
The area is given by the product of length and width
Suppose, w is the width of the area

Thus, the width of the rectangle is
