The length of a rectangular room is double of its breadth.If the area is 512 square inches , what is the perimeter ? Correct Answer 8 feet

ধরি, ঘরটির প্রস্থ = x ইঞ্চি ∴ দৈর্ঘ্য ,, = 2x ইঞ্চি প্রশ্নমতে, x × 2 x = 512 ⇒ x2   = 256 ⇒ x = 16 ∴ ঘরের প্রস্থ 16 ইঞ্চি ∴ ,, দৈর্ঘ্য = (16 ×  2) ,, = 32 ,, ∴ পরিসীমা = 2 (16 + 32) ইঞ্চি = 96 ইঞ্চি = 9612 ফুট = ৪ ফুট।
