Ben has 6 square tiles. Each tile has a width of 8 inches. He lays the tiles in a long row. What is the perimeter of the row of tiles?

The perimeter would be 112. That's the answer because after you multiply 6 and 8, you'll get 48. But you can't forget ℎ, ℎ and. In this case is 6. So you have to plug in;

ℎ: L = 8

ℎ: N•L = 6•8 = 48

So the perimeter is;

8 + 48 + 8 + 48 = 112
