The length of the rectangle is 5 cm 5 mm, and the width is 3 cm. Calculate the perimeter and area of the rectangle.

The length of the rectangle is 5 cm 5 mm.
The width of the rectangle is 3 cm.
Determine the perimeter and area of the rectangle. We write down the solution.
First, we translate the values into millimeters. 1 cm – 10 mm.
5 cm 5 mm = 50 mm + 5 mm = 55 mm.
3 cm = 30 mm.
Next, we find the perimeter of the rectangle. The perimeter is the sum of the lengths of all sides of the rectangle.
P = (a + b) × 2 = (55 mm + 30 mm) × 2 = 85 mm × 2 = 170 mm.
Next, we find the area of the rectangle. The area of the rectangle is equal to the product of the opposite sides.
S = a × b = 55mm × 30mm = 1650mm ^ 2.
Answer: P = 170 mm; S = 1650 mm ^ 2.
