Given:

The width of a rectangle is x centimeters and its length is (x+ 2) cm.

To find:

The expression for the perimeter of the rectangle.

Solution:

We know that, perimeter of a rectangle is

Perimeter=2(Length+Width)

We have,

Width = x cm

Length = (x+2) cm

Putting these values in the above formula, we get

Perimeter=2((x+2)+x)

Perimeter=2(2x+2)

Perimeter=2(2x)+2(2)

Perimeter=4x+4

Therefore, the required expression for the perimeter of the rectangle is (4x+4) cm.

 In order to figure out what the answer is you would have to divide the number of feet it fell by the time. If you do 35.75 divided by 3.25 it would be 11. 
So the answer most likely would be 11
Please correct me if I am wrong
