Answer:
800 tiles
Step-by-step explanation:
Area of the tiles = Length × Breadth
= 13 × 7
= 91 cm²
Area of the rectangular region = Length × Breadth
= 520 × 140
= 72800 cm²
Therefore the number of tiles needed to cover the rectangular region
= Area of the rectangular region ÷ Area of the tiles
= 72800 cm² ÷ 91 cm²
= 800 tiles
