Answer:
Width of the Rectangle = 3cm
Step-by-step explanation:
We know, Perimeter =20cm ; Length = 7cm ; Width = x
Therefore Perimeter of Rectangle = 2 (Length x Breadth) [Note: Width is same as Breadth ]
=> 20 = 2 ( 7 X x)
=> 20 = 14 X 2x
=> 2x = 20 - 14
=> 2x = 6
=> x = 6/2
=> x = 3
Conclusion, Width or Breadth of The Rectangle is 3cm
