Answer:
47x (square units)
Step-by-step explanation:
The given shape is made up of:
Area of the rectangle
= width × length
= 3x × 14
= 42x
Area of the triangle
= 1/2 × base × height
= 1/2 × (14 - 9) × (5x - 3x)
= 1/2 × 5 × 2x
= 5x
Area of given shape
= area of rectangle + area of triangle
= 42x + 5x
= 47x (square units)
