Answer:
38.6 units.
Step-by-step explanation:
The given figure is composed of a parallelogram and one semicircle.
We need to find the perimeter of the parallelogram.
Perimeter = sum of all sides
ATQ,
P = 9+8+9+(2πr/2)
i.e.

or
= 38.6 units
So, the perimeter of the figure is equal to 38.6 units.
Sqrt 70 < sqrt x < sqrt 75
sqrt of 64 = 8
sqrt of 81 = 9
8 < x < 9
8.4^2 = 70.56
8.5^2 = 72.25
8.6^2 = 73.96
sqrt 70 < sqrt (8.4^2 to 8.6^2) < sqrt 75
In expanded form, it would be 9*10 + 5*1 + 4 * 0.1 + 1 * 0.01 + 7 * 0.001. Hope this helps!
