Question

The length of a rectangle is represented by x+3 and the width by 2x-4. Write an expression for the area of this rectangle

Answer 1

Answer:

2x² +2x - 12

Step-by-step explanation:

area of rectangle = length X width

length = x+3

width = 2x - 4

Area = (x+3)(2x-4)

        = x(2x-4) +3(2x-4)

        = 2x² - 4x + 6x - 12

        = 2x² +2x - 12
