Answer 2

Answer:

800 tiles whose length and breadth are 13 cm and 7 cm respectively are needed to cover a rectangular region whose length and breadth are 520 cm and 140 cm.

Step-by-step explanation:

​According to the question we have:-

Given:

Length of tiles = 13cm

Breadth of tiles = 7 cm

Area of tiles = Length  x breadth = 13  x 7 =  91 sq. cm

Now  length of rectangular region = 520

and breadth = 140

Area of Rectangular Region = 520 × 140 = 72,800 sq. cm  

Required tiles = Area of rectangular region/area of tiles

= 72800/91  

= 800 tiles

Hence , the required tiles is 800.
