Question

Given a rectangle with length (2x + 1) meters and width (x - 3) meters.
Determine a simplified expression for the area of the rectangle.
Proper answer please!

Answer 1

Answer:

Ok we know that area of rectangle will be Length×Breadth.

so you have to multiply the first expression with another

Answer 2

$length = (2x + 1)m \\ breadth = (x - 3)m \\ area \: of \: rectangle = length \: \times breadth \\ = (2x + 1) \times (x - 3) \\ = 2x(x - 3) + 1(x - 3) \\ = 2 {x}^{2} - 6x + x - 3 \\ = 2 {x}^{2} - 5x - 3$
