Answer:
The area would be 2x^2 + 11x + 14.
Step-by-step explanation:
To find the area of a rectagular field, you will have to multiply the length by the breadth. Since the length is (2x + 7) and the breadth is (x + 2), you would have to solve (2x + 7) × (x + 2). To find the product, you will first have to multiply 2x and x. That would be 2x^2. Then, you multiply 2x and 2. That would be 4x. Then, you multiply 7 and x. That would be 7x. You then multiply 7 and 2 last. That would be 14. You should get 2x^2 + 4x + 7x + 14. That can also translate to 2x^2 + 11x + 14, which is the final answer.
