#### Answer

$width=23$ m and $length = 40$ m

#### Work Step by Step

Since we are given that perimeter = 126 m Formula to calculate the perimeter of a rectangle is : Perimeter= 2( Length + Width) or, $P= 2(l+w)$ Here, $l= 2w-6$ Thus, $126= 2 (2w-6+w)$ or, $126=4w-12+2w$ or, $126=-12+6w$ Thus, $width=23$ m and $length = 2w-6= 2(23)-6= 40$ m
