how to get the Area of the rectangle with the height of 5-x and a base of 2x+3

Just multiply them all I think because they are just similar to length and width and the formula for the are of the rectangle is Length x Width.

Area of the Rectangle = (5 - x) (2x + 3)
                                = -2x² + 7x + 15 units²
