Answer:
Step-by-step explanation:
This shape is actually just a rectangle with a missing triangle. We can first find the area of the rectangle with 
and subtract the triangle.
Area of missing triangle = 
(b is the base and h is the height)
Base = 
Height = 
Area of missing triangle = 
Area of the figure: 
--------------------------------------------------------------------------
Alternatively, you can find the area of each individual shape and add them all up.
Area of the rectangle: 
Area of square: 
Area of triangle: 
Total Area: 
Answer:
6:6 / 3:3 / 9:9
Step-by-step explanation:
1st answer: Divide both sixes by 2
2nd answer: Multiply by 1, it will be the same answer
3rd answer: Multiply both threes together

speed = distance/time
distance = speed * time
d = st
time up the mountain: t
time down the mountain: 6.6 - t
distance each way: d
Up the mountain:
d = st
d = 80t
Down the mountain
d = st
d = 85(6.6 - t)
The distances are equal, so
80t = 85(6.6 - t)
80t = 561 - 85t
165t = 561
t = 3.4
6.6 - t = 6.6 - 3.4 = 3.2
It takes 3.4 hours up the mountain and 3.2 hours down the mountain.
3.4 hours at 85 mph covers the same distance as 3.2 hours at 85 mph.
3.4 hours * 80 mph = 272 miles
3.2 hours * 85 mph = 272 miles
