Answer:

Area of rectangle:

4

12

Step-by-step explanation:

rectangle area = length * width

trapezium area = (upper base + lower base) * height / 2

2x * (x -1) + 3 = ( (x-1) + (2x+2)) * x / 2

2x^2 - 2x + 3 = ( 3x + 1) *x /2

2x^2 -2x + 3 = (3x^2 + x) / 2

  *2                                  *2

4x^2 - 4x + 6 = 3x^2 + x

-3x^2              - 3x^2

x^2 -4x +6 = x

-x                 -x

x^2 - 5x +6 = 0

factor

(x - 2) (x -3) = 0

x -2 = 0   or  x - 3 = 0

x = 2.            x  = 3

So the value of x can be 2 or 3

x = 2

   2(2) * (2-1)

= 4 *1

= 4

x = 3

  2(3) * (3-1)

= 6 * 2

= 12
