let the breath be X and length be 3x.
now,
given that
area =2(l+b)
588=2(x+3x)
588=2×4x
4x=588\2
4x=294
x=294/4
x=73.5
so, breath =73.5cm
and, length=3x=3×73.5= 220.5

let the breadth of paper be x
then length of paper will be 3x
area given = 588sq.cm
area of rectangular = length × breadth
=588=x×3x
=588=3x^2
=588/3=x^2
=196=x^2
=14=x
length of paper is 3x = 3×14
=42
