1. Answer

   Length is 20 m and Breadth is 16 m

   Let the width of the garden =x meter

   Then length=(x+4) meter

   Half perimeter =36 m

   So perimeter of garden =(2×36)=72 meters

   According to the question

   ⇒2(l+b)=72

   ⇒2(x+x+4)=72

   ⇒2x+2x+4=74⇒4x=64⇒x=16 meters

   Hence,the width of the garden =16 meters

   The length of the garden =(16+4)=20 meters
