Question

Can you help me solve this problem? 

Let I be the length of a diagonal of a rectangle whose sides have lengths a and y, and assume that a and y vary with time.
If z increases at a constant rate of ft/s and y decreases at a constant rate of ft/s, how fast is the size of the diagonal changing when
x =1 ft. and y = 6 ft?
