Area of a triangle is equal to 1/2 b(h) so since you already have the height and base, all you need to do is input it back into the equation:

(10)(13)
Multiply 10 & 13 to equal

(130)
Then take half of 130 to get
A = 65

Step-by-step explanation:
Given

Required
Draw the graph
First, we identify at least 2 possible values of x and y
Let 
Solve for y




So, a point is: 
Let 
Solve for y





So, another point is: 
<em>Plot </em>
<em> and </em>
<em> on the graph, then draw a straight line through both points</em>

Answer:
1:1.5
Step-by-step explanation:
We have that 150 meters in the reality and the new size in the drawing is 2/3, therefore
150mtrs(old) * 2/3 = 100mtrs(new), also 100 mtrs. in the drawing are 150mtrs. in the reality or 1 is to 1.5
