Answer:

$564$ tiles

Step-by-step explanation:

there are many ways to solve this soo...

1. convert to centimetres (there are 100 centimetres in 1 metre)

2. the square tiles area = $20*20=400cm$

2. find the large area (4.8m x 3.8m or 480cm x 380cm)

$480 *380=182400cm$

2. find the two smaller areas (1.2m x 1.8m or 120cm x 180cm)

$2(120*180)=4.3200cm$

3. add to find total area

$182400 +43200=225600cm$

4. find how many tiles are needed

$\frac{225600}{400}= 564$ tiles
