View all: BANGLADESH BANK BANKERS | WRITTEN QUESTION (MATH) SOLVE | 1986

Correct Answer: উত্তরঃ ২১.৩৩ গজ কার্পেট লাগবে ।

Explanation:

১২ বর্গ ফুট বর্গাকার ঘরটির ক্ষেত্রফল = (১২ × ১২) ফুট=১৪৪ বর্গফুট

কার্পেটের প্রস্থ, ২৭ ইঞ্চি=$\frac{২৭}{১২ }$ফুট

কার্পেটের দৈর্ঘ্য=$১৪৪ \div \frac{৯}{১৪}$

=২১.৩৩ গজ
