Answer: 200 mm
Step-by-step explanation:
The perimeter of rectangle is given by :-
[tex]P=2(l+w)[/tex], where l is length and w is width of the rectangle.
Given : Two sides of a rectangle are 4 cm in length. The other two sides are 6 cm in length.
The perimeter of the rectangle will be :_
[tex]P=2(4+6)=2(10)=20\ cm[/tex]
We know that 1 cm = 10 mm
Therefore, perimeter of the rectangle = [tex]20\times10=200\ mm[/tex]
