Final answer:
The approximate area of the playpen is 3.14 square meters.
Step-by-step explanation:
The area of a circle can be found using the formula A = πr², where A is the area and r is the radius. In this case, the playpen has a diameter of 2 meters, so the radius is half of the diameter, or 1 meter. Using the approximation of pi as 3.14, we can calculate the approximate area of the playpen:
A = 3.14 × (1 meter)² = 3.14 square meters
Therefore, the approximate area of the playpen is 3.14 square meters.
