Answer: Length = 11 cm
Width = 14 cm
Step-by-step explanation:
Let x = Length of the rectangle.
then, width = x+ 3
Perimeter of rectangle = 2 (length +width)
Then, Perimeter = 2 (x+x+3)
= 2 (2x+3)
Since perimeter = 50 cm

[Divide both sides by 2]

The dimensions are :
Length = 11 cm
Width = 11+3= 14 cm
