The perimeter of a rectangle whose sides are lengths (3z+2) units and (2z+3) units

P = 10z + 10 units.

Step-by-step explanation:

To find the perimeter of a rectangle, you can use the formula P = 2l + 2w.

If one side is '3z + 2' and the other is '2z + 3', we can plug these into the equation:

P = 2 (3z + 2) + 2 (2z + 3).

Distributing the 2's gives us:

P = 6z + 4 + 4z + 6

Combine like terms, resulting in the final answer:

P = 10z + 10 units.
