Answer:
Step-by-step explanation:
In order to find the value of y, first we need to find the length of the perpendicular dropped from one of the vertices of the triangle to its opposite side.
By geometric mean theorem:
Length of the perpendicular
Next, by Pythagoras theorem:

399.6 square meters
7•8/2=28
28•3=84
8•6.9/2=27.6
(12•8)•3=288
84+27.6+288=399.6
Here we want to find the equation of the line containing the median CP.
P, being the midpoint of AB can be found using the midpoint formula as:

.
The slope m of the line through CP can be found by the slope formula using points C(18, -8) and P(0, 1):

.
Now, we can write the equation of the line with slope -1/2, passing through
P(0, 1):

.
