Answer:
Perimeter of rectangle = 140 cm.
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.
