The area of a rectangle is x%5E2-x-2 and the length of this rectangle is x-what?

The problem description is incomplete.

The area of a rectangle is x squared minus x minus 2 and the length of the rectangle is x minus.
a. find the width of the rectangle.
b. Find the area of the rectangle of the width is 4 m
Since area = x%5E2+-+x+-+2, then dimensions MUST be (x - 2) and (x + 1).

Now that you know this, determine its length. You can also determine the answer to "b."

Note that x MUST BE > 2.
