Question

Calculate the perimeter of a rectangle with a length of 17.5 cm and a width of 40 mm in cm

Answer 1

Answer: 43 cm

Step-by-step explanation:

The perimeter of rectangle is given by :-

$P=2(l+w)$, 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= $\dfrac{40}{10}\ cm=4\ cm$

Then, the  perimeter of rectangle will be :-

$P=2(17.5+4)\\\\\Rightarrow\ P=2(21.5)\\\\\Rightarrow\ P=43\ cm$

Hence, the perimeter of rectangle = 43 cm
