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

Perimeter of rectangle = 140 cm.

Step-by-step explanation:

As we know that,

Rectangle is defined as a quadrilateral having opposite sides are equal and each angle are at 90°.

Let the length of rectangle = l

And the width = b

Therefore,

Perimeter of rectangle is given by = 2 (l × b)

From the question,

Given:

length = l = 17.5 cm

Width = b = 40 mm = 4 cm

( because 1 cm = 10 mm)

Perimeter of rectangle is given by = 2 (l × b) = 2(17.5 × 4) = 140 cm.

Hence, the perimeter of rectangle = 140 cm.

450 is the final answer! : )
