Answer:

  • Given Below

Explanation:

area of rectangle: length * width

                            :  5x * (x + 3)

                            : 5x² + 15x

area of square: length * length

                        : 3x * 3x

                        : 9x²

Difference: area of rectangle - area of square

                 : 5x² + 15x - 9x²

                 : - 4x² + 15x

i)

when x = 1

- 4x² + 15x

- 4(1)² + 15(1)

11

ii)

when x = 2

- 4x² + 15x

- 4(2)² + 15(2)

14

iii)

when x = 3

- 4x² + 15x

- 4(3)² + 15(3)

9

c)

The difference comes as negative value.
