The length of room is 1.5 times of its breadth. If the area of the room is 216 sq. meters , what is the perimeter of the room ? Correct Answer 60 meter

ধরি, ঘরটির প্রস্থ = x মিটার ,, দৈর্ঘ্য = 1.5x = 3/2x মিটার প্রশ্নমতে, x × 32 × x = 216  ⇒ x2 = 216 × 23⇒ x2 = 144 ⇒ x = 12 প্রস্থ = 12 মিটার. দৈর্ঘ্য = 3/2 × 12 = 18 মি. পরিসীমা = 2(12 + 18) মিটার = 60মিটার
