রাস্তাসহ বাগানের দৈর্ঘ্য ৫ মিটার ।
রাস্তাসহ বাগানের প্রস্থ মিটার ।
রাস্তাসহ বাগানের ক্ষেত্রফল বর্গমিটার ।
শুধু বাগানের ক্ষেত্রফল বর্গমিটার।
∴ রাস্তার ক্ষেত্রফল = ৪৭৫ - ৩১৫ = ১৬০ বর্গমিটার।
অতএব, মোট খরচ হবে টাকা।

মনে করি, গাছের উচ্চতা AB = h মিটার। পাদবিদ্ B থেকে 20 মিটার দূরের অপর একটি বিন্দ C. তাহলে BC = 20 মি.। C কিন্দতে গাছটির শীর্ষের উন্নতি কোণ ∠ACB = 30°.
এখন, ∆ABC-এ
বা,
∴ h = 11.55
∴ মিনারটির উচ্চতা অথবা 11.55 মিটার।
উত্তর: 11.55 মিটার।
