Correct Answer: উত্তরঃ নির্ণেয় সর্বাপেক্ষা বড় আয়তাকার কার্পেটের পরিমাণ হবে ৬০ বর্গমিটার ।

Explanation:

১ম হলঘরের দৈর্ঘ্য ৩০ মিটার এবং প্রস্থ ১২ মিটার

ক্ষেত্রফল (১২X৩০) বর্গমিটার =৩৬০ বর্গামটার

২য় হলঘরের দৈর্ঘ্য ২০ মিটার এবং প্রস্থ ১৫ মিটার

ক্ষেত্রফল=২০X১৫=৩০০ বগামিটার

নির্ণয় সর্বাপেক্ষা বড় আয়তাকার কার্পেটের পরিমাণ হবে ৩৬০ এবং ৩০০ এর গ.সা.গ।

সুতরাং গ.সা. গু = ৬০
