calculate the perimeter to the nearest tenth​

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
