Answer:

Pls instead of giving thanks. Mark as brainliest of it helps.  Ans :  150 tiles

Step-by-step explanation:

It is very simple.

First, we will find the area of the marble slab:

L* b = 20 * 30 = 600 cm ²

Then find the area of square :

S² = 3² = 9 meters ²

Now divide them ;

9 m²/ 600 cm²     { 1 m² = 10000 cm²}

90000/ 600 = 150 tiles
