A 16 by 18 foot rectangular section of a wall will be covered by square tiles that measure 2 feet on each side. If the tiles are not cut, how many of them will be needed to cover the section of the mall?

72 tiles

Step-by-step explanation:

16 x 18 = 288ft.2

2 x 2 = 4ft.2

288 divided by 4 = 72 tiles

Since 288 is the space of the wall, each tile has an area of 4 feet squared, so 288 divided by 4 would make it so they need 72 tiles.

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1
