# Easy Geometry & Mensuration Solved QuestionAptitude Discussion

 Q. How many tiles whose length and breadth are 12 cm and 5 cm respectively will be needed to fit in a rectangular region whose length and breadth are respectively 144 cm and 100 cm:
 ✖ A. 160 ✔ B. 240 ✖ C. 320 ✖ D. 450

Solution:
Option(B) is correct

Total area of the region

$=100\times 144$

$=14400\text{ cm}^2$

Area of one tile

$=12\times 5$

$=60\text{ cm}^2$

Number of tiles required

$=\dfrac{14400}{60}$

$=240$

Therefore, 240 tiles are required.

Edit: Thank you Pawan Sharma, added rectangular region's length and width in order to complete the question.
