Good luck !

Answer 2

Answer:

Length=45cm Breadth=15cm

Step-by-step explanation:

Breadth=x

Hence length=3x

Perimeter=120cm

Perimeter of rectangle= 2×(l+b)

120=2×(3x+x)

120/2=4x

4x=60

x=60/4

x=15

Hence breadth comes out to be 15cm, hence length will be 3×15=45cm

Hope this helps you. Have a nice day buddy!
