Lucy is laying tile around the edge of a counter that is 6.4 feet by 2.7 feet. If each tile is 6 inches long, and Lucy buys 30 t
polet [3.4K]

Answer:

Tiles won't be enough

Step-by-step explanation:

The perimeter of the area :

2(length + Width)

Given dimension = 6.4 by 2.7 feets

Perimeter = 2(6.4 + 2.7) = 18.2 feets

1 feet = 12 inches

Perimeter = 18.2 * 12 = 218.4 inches

1 tile = 6 inches

30 tiles = 6* 30 = 180 inches

Since the perimeter of the area is greater Than the 180, then we can conclude that the tiles won't be enough
