The area of an 8-1/2" x 11" piece of paper is 93.5 sq. inches.
If there are 11 strips the average area will be the total area of all strips 93.5 sq. inches / 11 strips, or
93.5 sq inches / 11 strips = 8.5 square inches
Therefore the correct answer is a. 8-1/2 sq. in.

Easy one.
If the sheet is 8 1/2 x 11 and in 11 different parts, all you do is divide the total area by 11. In this case
8 1/2 x 11
____________
11
The 11's cancel each other out, leaving 8 1/2 per piece as your average.

The answer is a: 8 and a half square inches. (8+1/2) * 11 / 11 = (8+1/2).

The area of the sheet is: A = 8.5*11 = 93.5 square inches. Then, divide this by 11 to find the average size of one strip. You get 8.5 square inches again. That's the answer.
Hope this helps!

I believe the answer is (a).
I found the area of the whole sheet of paper
area of rectangle = length * width
= 11 * 8.5
= 93.5 sq. in
then I divided it by 11
93.5/11 =8.5 sq. in
