breadth=2.25cm

lenght=6.75cm

Step-by-step explanation:

let breadth =x cm . therefore length =3x cm( as mentioned in the question).

using formulae of area of rectangle that is

 = 2(l + b)

now substituting the values , we get

2(3x+×)=18

4x=18÷2

x=9÷4=2.25

therefore breadth =2.25cm

so length =3x= 3×2.25=6.75

therefore length =6.75cm
