Answer:
The slopes of line segments AC and AD are same or constant i.e 
Step-by-step explanation:
We need to find slopes of AC and AD and tell if they are same or not.
The formula used to calculate slope is: 
Finding slope of AC
We have A=(3,2) and C=(0,1)
Finding slope using formula:
We have 

So, Slope of AC is 
Finding slope of AD
We have A=(3,2) and C=(9,4)
Finding slope using formula:
We have 

So, Slope of AD is 
So, the slopes of line segments AC and AD are same or constant i.e 
First,
, and if we multiply
by
we get

Subtracting this from the numerator gives a remainder of

Next,
, and if we multiply
by
we have

and subtracting this from the previous remainder, we end up with a new remainder of

Next,
, and if we multiply
by
we get

Subtracting from the previous remainder, we get a new remainder of

which contains no more factors of
, so we're done.
So,

Area of triangle = 1/2 x base x height
Let the base be "b"
90 = 1/2 x 10 x b
90 = 5b
b = 18 ft
Base = 18 ft
Each as a fraction 42/100 35/100 18/100 100/100
