an the area according to the problem is equal to , so:

Factoring the expression:

clearing for :

and

since we are talking about sides of a rectangle we can ignore the negative sign in -18, and the dimensions of the rectangle are:

x

which when multiplied give the of area.

the answer is a

step-by-step explanation:

because your just changing the position of where the shape is
