A garden is 24 m long and 14 m wide. There is a path 1 m wide outside the garden along its sides. If the path is to be constructed with square marble tiles 20 cm × 20 cm, the number of tiles required to cover the path is
(a)200
(b)1800
(c)2000
(d)2150
Answer
Answer (as printed): C
Explanation
Area of the path $=[(26\times16)-(24\times14)]$ m$^2=(416-336)$ m$^2=80$ m$^2$. $\therefore$ Number of tiles required to cover the path $$=\frac{\text{Area of path}}{\text{Area of each tile}}=\left(\frac{80\times100\times100}{20\times20}\right)=2000.$$
