Answer: 43 cm
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 : The length of rectangle is 17.5 cm and the width is 40 mm in cm.
Since , 1 cm = 10 mm
Then, 40 mm= [tex]\dfrac{40}{10}\ cm=4\ cm[/tex]
Then, the perimeter of rectangle will be :-
[tex]P=2(17.5+4)\\\\\Rightarrow\ P=2(21.5)\\\\\Rightarrow\ P=43\ cm[/tex]
Hence, the perimeter of rectangle = 43 cm
