Answer: the perimeter is 40.9 ft
Step-by-step explanation:
The given figure is a trapezium. It is made up of a rectangle and a right angle triangle.
The perimeter of the trapezium is the distance around the figure. This means that the inner dimensions are not included.
Since the opposite sides of the rectangle are equal, it means that the base of the trapezium would be
10 + 4 = 14 ft
Therefore, the perimeter of the trapezium would be
8 + 10 + 8.9 + 14 = 40.9 ft

The area of the deck is 413 square feet
<h3>How to determine the area of the proposed deck?</h3>
Start by calculating the area of the outer rectangle using:
Area = Length * Width
This gives
Area1 = (18 + 12) * (16 + 8)
Area1 = 720
Next, calculate the area of the inner rectangle using:
Area = Length * Width
This gives
Area2 = 16 * (18 + 8)
Area2 = 416
Subtract these areas
A1 = Area1 - Area2
A1 = 720 - 416
A1 = 304
Next, calculate the area of the outer semicircle using:
Area = 0.5πR²
This gives
Area1 = 0.5 * 3 * (12-1)²
Area1 = 181.5
Next, calculate the area of the inner semicircle using:
Area = 0.5πr²
This gives
Area2 = 0.5 * 3 * (7)²
Area2 = 73.5
Subtract these areas
A2 = Area1 - Area2
A2 = 181.5 - 73.5
A2 = 108
Add A1 and A2
A = 304 + 108
Evaluate the sum
A = 412
Hence, the area of the deck is 413 square feet
