• # question_answer A flooring tile has the shape of a parallelogram whose base is 24 cm and the corresponding height is 10 cm. How many such tiles are required to cover a floor of area $1080\,{{m}^{2}}$? (If required you can split the tiles in whatever way you want to fill up the corners). A) 30,000               B)        40,000C) 45,000  D)       60,000E) None of these

Solution :

Explanation Option [c] is correct. Area of the Parallelogram $\text{=base }\!\!\times\!\!\text{ height=24 }\!\!~\!\!\text{ }\!\!\times\!\!\text{ 10=240 sq cm}$ Required number of tiles =$\frac{Area\,\,of\,\,Floor}{Area\,\,of\,\,Tiles}=\frac{1080\times 100\times 100}{240}=45000$
