Answer:

Step-by-step explanation:

Area of a rectangle = (l*b)

= (2x+5)(x+y+2)

= 2x*x + 2x*y + 2x*2 + 5*x + 5*y + 5*2

= 2x^2+2xy+9x+5y+10

Hope you understood!!

Answer:

2x² + 2xy + 9x + 5y + 10 units²

Step-by-step explanation:

The formula for area of rectangle is Length x Base.

We need to expand the given equation.

(2x + 5) (x + y + 2)

First, multiplying 2x with x, y & 2, we get,

2x² + 2xy + 4x. ------ (1)

Now, multiplying 5 with x, y & 2, we get,

5x + 5y + 10. ------- (2)

Adding 1 and 2,

=> 2x² + 2xy + 4x + 5x + 5y + 10

=> 2x² + 2xy + 9x + 5y + 10 units²

Hope it helps :)
