Answer: 187

Explanation:

Given

Dimension of stone is
$1\ m* 80\ cm$

Dimension of compound
$13.6\ m* 11\ m$

Area of the stone

$\Rightarrow a=1* 0.8=0.8\ m^2$

Area of compound

$\Rightarrow A=13.6* 11=149.6\ m^2$

No of the stones needed is

$\Rightarrow n=(A)/(a)\\\\\Rightarrow n=(149.6)/(0.8)\\\\\Rightarrow n=187$

Thus, 187 stones are needed
