It’s b what u need to do is 13x9 which is 117 then divide it by 2 which is 58.5
Let r = usual driving rate
let t = usual driving time
We need to figure out t
The distance she covers in her usual time at her usual rate is r*t
The distance she covers in her new time at her new rate is:
(1+t)*((2/3)r)
Set this equal to each other and solve for t.
rt = (2/3)r + (2/3)rt
(1/3)rt = (2/3)r
(1/3)t = (2/3)
t = 2
So her usual time is 2 hours. (There's probably a faster way to do this)

By angle bisector property:

Answer:
See explanation.
Step-by-step explanation:
To find the area of a parallogram, do A=Bh where a is the area, b is the base, and h is the height.
In this case, b is 9 cm while h is 6 cm. Do A=Bh by multiplying 9 cm by 6 cm. This will give us 54 cm².
The measurement we didn't use is the measure of the diagonal parts of the quadrilateral which, in this case, was 7.5 cm.
