A
$4290$
💡 Explanation:
The edge of rectangular veranda are $18\ m\ 72\ cm=1872\ cm$ and $13\ m\ 20\ cm=1320\ cm$.
On taking $HCF$ of $1872$ and $1320$, we get
$HCF=24$
Therefore,
No. of tiles required $=$ $\dfrac{Area\ of\ Veranda}{Area\ of\ tiles}$
$=\dfrac{1872\times 1320}{24\times 24}$
$=4290$
Hence, this is the answer.
