Answer:The length of closet is 5 ft.

Step-by-step explanation:

Let the length of closet is x ft.

It is given Jackson's bedroom area is 9 times that of the closet.

The area of bedroom is given as 90 square feet ans width of closet is 2 ft.

Or 90=9( 2 times x)

Or 90 =18 x

Dividing both sides by 18 we have

x=5 ft .

The length of closet is 5 ft.
