ধরি, 
ঘরটির প্রস্থ = x মিটার
,,  দৈর্ঘ্য = 1.5x = 3/2x মিটার
প্রশ্নমতে, $$\begin{gathered} x\times \frac{3}{2}\times x=216 \\ \Rightarrow x2=\frac{216\times 2}{3} \\ \Rightarrow x2=144 \\ \Rightarrow x=12 \end{gathered}$$
প্রস্থ = 12 মিটার.
দৈর্ঘ্য = 3/2  ×  12 = 18 মি.
পরিসীমা = 2(12  +  18) মিটার = 60মিটার
