The length of the entire rectangle is 10, and its width is 6. The length of the smaller rectangle is 6, and its width is 2. If you multiply 10 by 6, you get 60 for the area of the entire rectangle. But since it just wants the shaded region, you now need to find the product of the non-shaded rectangle and then subtract it from the whole rectangle to get the area of the shaded region. 6 x 2 = 12 60 - 12 = 48. Sorry if it sounded confusing let me know if you need simplified, and I hope this helps.
