Answer:

47x  (square units)

Step-by-step explanation:

The given shape is made up of:

  • a rectangle
  • a triangle

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)
