Answer:

369.5 ft²

Explanation:

Separate the figure into 2 rectangles and 2 triangles.

(see attached image)

Area 1

Area of a rectangle = width × length

= 4 × 5

= 20 ft²

Area 2

Area of a rectangle = width × length

= 8 × (4 + 4 + 5)

= 8 × 13

= 104 ft²

Area 3

Area of a triangle = 1/2 × base × height

= 1/2 × (6 + 4 + 5 + 4 - 6) × 23

= 1/2 × 13 × 23

= 149.5 ft²

Area 4

Area of a triangle = 1/2 × base × height

= 1/2 × 8 × (21 + 8 - 5)

= 1/2 × 8 × 24

= 96 ft²

Total Area

Area 1 + Area 2 + Area 3 + Area 2 = 20 + 104 + 149.5 + 96

= 369.5 ft²
