Given:
The width of a rectangle is x centimeters and its length is (x+ 2) cm.
To find:
The expression for the perimeter of the rectangle.
Solution:
We know that, perimeter of a rectangle is
[tex]Perimeter=2(Length+Width)[/tex]
We have,
Width = x cm
Length = (x+2) cm
Putting these values in the above formula, we get
[tex]Perimeter=2((x+2)+x)[/tex]
[tex]Perimeter=2(2x+2)[/tex]
[tex]Perimeter=2(2x)+2(2)[/tex]
[tex]Perimeter=4x+4[/tex]
Therefore, the required expression for the perimeter of the rectangle is (4x+4) cm.
