40 inches because a rectangle has 2 sets of parallel lines and if the width and length are 10 then you just have to add up all the sides.

Since we are translating this graph one unit to the right, replace x with (x-1)
Note: If you are translating a graph to the left by k units, replace x with (x+k), and if by the right, replace x with (x-k)

After simplifying, we now have the following equation:

This is the new equation. Let me know if you need any clarifications, thanks!
