Answer:
Explanation:
To find the area of the enlarged trapezium, we first need to find the area of the original trapezium. The vertices of the original trapezium are (-9, 3), (-9, 0), (-3, 6), and (-3, -3) . Using the distance formula, we can find that the length of the top base is 6 units and the length of the bottom base is 9 units. The height of the trapezium is 9 units. Therefore, the area of the original trapezium is:
Area = (1/2) x (6 + 9) x 9
= 67.5 square units

To find the area of the enlarged trapezium, we need to multiply the area of the original trapezium by the square of the scale factor. The scale factor is 2.6. Therefore, the area of the enlarged trapezium is:
Area = 67.5 x (2.6)^2
= 456.3 square units (rounded to one decimal place)

Therefore, the area of the enlarged trapezium is approximately 456.3 square units.
