Each of those boxes has a length and a width of .1
So the width (smaller side) of the shaded rectangle is 3 of those boxes or 3 x .1
That gives you a width of .3
Then, the length (bigger side) of the shaded rectangle has a length of 8 boxes. Each of these boxes is .1 so the total length is 8 x .1 = .8
This totals to an area of .8 x .3

Answer: .8 x .3

Hope this helps :)
