Answer: 43 cm
Explanation:
The perimeter of rectangle is given by :-
, 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=
![(40)/(10)\ cm=4\ cm](https://img.qammunity.org/2020/formulas/mathematics/college/eazxwpebgzuwx6ryngvs5o45yso1ox0tvi.png)
Then, the perimeter of rectangle will be :-
![P=2(17.5+4)\\\\\Rightarrow\ P=2(21.5)\\\\\Rightarrow\ P=43\ cm](https://img.qammunity.org/2020/formulas/mathematics/college/1d3tq3cdaol2qurnt0fmds9uzmti0bf89a.png)
Hence, the perimeter of rectangle = 43 cm
