Two ✖ squared is equals to fourteen ✖ -nine
​

14

Step-by-step explanation:

Given:

diameter of circle x = 22 units

diameter of circle y = 16 units

wx = 15 units

Want to find: length of xy

First, I started out by halving the diameters to get to the length of the radii, as that's what was depicted in the problem:

circle x: 22/2 = 11

circle y = 16/2 = 8

Now, you just strategically add..

5 + (11-5) + (8-5)

5 + 6 + 3 = 14 units
