Question

find the area of a rectangular field whose length is (2x + 7) and is (x + 2) m​

Answer 1

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.

Answer 2

Answer:

are of the rectangle= l* b

are of the rectangular field= (2x+7) (x+2)

=2xsquare+4x+7x+14

=2xsquare+11x+14

you can further solve by middle term splitting
