Given that the length is twice the width, Then : L = 2W .....(1) Let the perimeter be P. ==> 2L + 2W = P ==> 2L + L = P ==> 3L = P Therefore the perimeter of the rectangle is three times it's length. 3 Tanish Chudiwal answered this dear friend an auditorium can be counted only in square metres or cubic metres. kindly specify your question. -3 Kriti Agrawal answered this Sorry Tanish but it is not mentioned in the book 0 Lakshya Agarwal answered this 3l=P -5
