City planners are designing a new dog park. The park will be a square. The area of the park is the square of the side length: area=2802 feet2. Without using a calculator, what is the area of the dog park? Use polynomial identities to support your answer. (thank you)

Step-by-step explanation:

A = 280² ft²

A = (200 + 80)² ft²

A = [200² + 2(200)(80) + 80²] ft²

A = (40000 + 32000 + 6400) ft²

A = 78400 ft²
