The base of a rectangle is three times as long as the height. If the perimeter is 64, what is the area of the rectangle? Correct Answer 192

মনেকরি, আয়তক্ষেত্রের উচ্চতা = h .:. আয়তক্ষেত্রের ভূমি = 3h তাহলে, পরিসীমা = 2(h + 3h) = 2 x 4h = 8h প্রশ্নমতে, 8h = 64 ⇒ h = 8 .:. আয়তক্ষেত্রের উচ্চতা = ৪ এবং ভূমি = 3 × 8 = 24 তাহলে আয়তক্ষেত্রের ক্ষেত্রফল = ভূমি উচ্চতা = 24 x 8 = 192
