Answer:
72.6 cm
Step-by-step explanation:
It is the perimeter of the overall rectangle plus twice the depth of the notch.*
P = 2(L+W) +2d
P = 2(16 cm + 13 cm + 7.3 cm) = 2(36.3 cm)
P = 72.6 cm
The perimeter of the shape is 72.6 cm.
_____
* You may be able to visualize this if you imagine the bottom (top) of the notch translated out (down) to the edge of the rectangle. That translation does not affect the length of the line segment, but helps convince you that only the two legs of the notch are added to the perimeter of the rectangle.

Answer:
A. 2006
Step-by-step explanation:
Given:
Number of male drivers model by equation ![y = 961.98x + 76820.54](https://tex.z-dn.net/?f=y%20%3D%20961.98x%20%2B%2076820.54)
Number of female drivers model by equation ![y = 1296.36x + 68162.65](https://tex.z-dn.net/?f=y%20%3D%201296.36x%20%2B%2068162.65)
Where
⇒ the number of years since 1980
We need to find when will the number of licensed male drivers in the U.S. equal the number of licensed female drivers in the U.S.
Solution:
Now we can say that;
to find number of years when the number of licensed male drivers in the U.S. equal the number of licensed female drivers in the U.S we need to make both the equation equal we get;
![961.98x + 76820.54=1296.36x + 68162.65](https://tex.z-dn.net/?f=961.98x%20%2B%2076820.54%3D1296.36x%20%2B%2068162.65)
Now Combining the like terms we get;
![1296.36x -961.98x =76820.54- 68162.65\\\\334.38x=8657.89](https://tex.z-dn.net/?f=1296.36x%20-961.98x%20%3D76820.54-%2068162.65%5C%5C%5C%5C334.38x%3D8657.89)
Now By using Division property dividing both side by 334.89 we get;
![\frac{334.38x}{334.38}=\frac{8657.89}{334.38}\\\\x= 25.89 \approx 26 years](https://tex.z-dn.net/?f=%5Cfrac%7B334.38x%7D%7B334.38%7D%3D%5Cfrac%7B8657.89%7D%7B334.38%7D%5C%5C%5C%5Cx%3D%2025.89%20%5Capprox%2026%20years)
Now x is number of years after 1980.
So we can say that;
26 years after 1980 is 2006.
Hence Approximately in the year 2006 the number of licensed male drivers in the U.S. equal the number of licensed female drivers in the U.S.
