| 1. First, let’s calculate the length of this rectangle. To do this, we will double its width, that is, multiply 4 by 2:
4 x 2 = 8 (cm).
2. Next, we find the perimeter of this rectangle, which, as you know, is equal to the sum of twice the length and twice the width:
2 x 8 + 2 x 4 = 24 (cm).
3. Finally, let’s calculate the area. To do this, multiply the length of the rectangle by its width:
8 x 4 = 32 (cm²).
Answer: The perimeter of this rectangle is 24 cm, and the area is 32 square centimeters.
