Answer: 
Step-by-step explanation:
The equation of the line is Slope-intercept form is:

Where "m" is the slope and "b" the y-intercept.
The slopes of perpendicular lines are negative reciprocal.
Then, if the slope of the first line is -3, the slope of the other line must be:

Substitute the point (3,4) into the equation and solve for b:

Then the equation of this line is:

The point P could be located in quadrant I, quadrant IV and the x-axis
<h3>How to determine the quadrant?</h3>
The coordinate of point P is given as:
P = (a, b)
Where a is positive
When a is positive, then the likely locations of P are:
- On the x-axis, when b = 0
- In quadrant I, when b is positive
- In quadrant IV, when b is negative
Hence, point P could be located in quadrant I, quadrant IV and the x-axis

Answer:
21
Step-by-step explanation:
A=1/2bh
252=1/2(24)(h)
multiply 1/2 and 24
252=12(h)
divide ( 252/12 12/12)
h=21
