The width of the rectangle is 1 cm 6 mm and it is 4 mm less than the length. Calculate the Perimeter and area of the rectangle.

First, let’s define the width of the rectangle:
1 cm 6 mm – 4 mm = 1 cm 2 mm.
The perimeter of a rectangle is the sum of the lengths of all its sides. The perimeter can be easily obtained using the formula:
(length + width) * 2 = (1 cm 6 mm + 1 cm 2 mm) * 2 = (2 cm + 8 mm) * 2 = 5 cm 6 mm.
The area of a rectangle is defined as the product of the width of the rectangle by its length:
1cm 6mm * 1cm 2mm = 16mm * 12mm = 192 sq. mm.
Answer: the perimeter of the rectangle is 5 cm 6 mm, and its area is 192 sq. mm.
