Question 920382
length is 4 meters longer than its width.
let x be the length of the garden
    y be the wide 
  x  = y+4
  but permiter  =62 m
     2(x+y)= 62
    2( (y+4)+y )=62
     2y+4= 62/2 
     2y+4  =31
       2y= 31-4
        2y= 27 m
       y= 27/2
        y= 13.5 m
    x=  y+4
          =13.5+4
           =17.5 m 
  so length  =  17.5  m
