To find the area of the quadrilateral, we first need to find the individual areas of the rectangle and triangle, and then add them together.
Area of the rectangle = length × width
Area of rectangle = 9 cm × 6 cm = 54 cm²
To find the area of the triangle, we use the formula:
Area of triangle = (base × height) / 2
Area of triangle = (4 cm × 5 cm) / 2 = 20 cm²
Now we add the areas together:
Total area of the quadrilateral = area of rectangle + area of triangle
Total area = 54 cm² + 20 cm² = 74 cm²
Therefore, the area of the quadrilateral is 74 cm².
