<span>In a triangle the sum of two sides is always greater than the third side.
9-9 < x < 9+9
0 < x < 18 </span>← answer
We know area of triangle = 
In triangle ABC , AB is the base and BC is the height
Now we find the distance between A and B
Distance formula is 
A(0,3), B(7,3)
Distance AB = 
=
= 7
B(7,3), C(7,7)
Distance BC = 
=
= 4
area of triangle = 
area of triangle = 
=
= 14 
Divide both the numerator and denominator by the GCD so it’s 12/1
I think the rang numbers are -2 , 2 , -4 , and 2. i hope that correct.
The two ways to find the ratio of the length is to turn the inches into feet or the feet into inches
So the answer can be solved like this:
1/36ft to 1/4ft which is 9:1 (blueprint size to actual size)
or
1/3in to 3in which is also 9:1 (blueprint size to actual size)
