Answer:
Therefore Dalia can install, before running out of tiles, the number of full rows = 29 rows.
Step-by-step explanation:
Dalia has 152 tiles
19 tiles broke.
Left are = 152 - 19 = 133 tiles
Therefore Dalia can install tiles for the number of rows with unbroken tiles = 133 / 4.5 = 29.56
Therefore Dalia can install, before running out of tiles, the number of full rows = 29 rows.
