# A lawn is rectangular and measures 36 m by 27 m. If one bag of fertiliser covers 360 m², how many bags must be purchased ?

Please find below the solution to the asked query :

$\mathrm{Area}\mathrm{of}\mathrm{lawn}=36\times 27{\mathrm{m}}^{2}\phantom{\rule{0ex}{0ex}}\mathrm{Now}\mathrm{one}\mathrm{bag}\mathrm{covers}\mathrm{area}=360\mathrm{m}{}^{2}\phantom{\rule{0ex}{0ex}}\mathrm{So}\mathrm{Number}\mathrm{of}\mathrm{bags}=\frac{36\times 27}{360}=2.7\phantom{\rule{0ex}{0ex}}\mathrm{So}3\mathrm{bag}\mathrm{must}\mathrm{be}\mathrm{purchased}.$
