A concert hall is in the shape of a rectangle. Its floor has a length of (x + 6) meters and a width of (2x  3) meters.
Which of the following simplified expressions represents the area of the floor? A.) 2x² + 9x  18 B.) 2x² + 15x  18 C.) x² + 5x  18 D.) x² + 9x + 18
Area of a rectangle = length x width
Area = (x + 6)(2x  3) = 2x²  3x + 12x  18 {used FOIL method / distributive property} = 2x² + 9x  18 {combined like terms} A.) 2x² + 9x  18 Ask Algebra House Comments are closed.
