Answer:
um I did the math and I got 5, so i dont really understand
Answer:
you want me to round it I will edit it and show you
Step-by-step explanation:
Try writing it in point-slope form and you will see why you have a problem.
slope m is equal to (y2-y1)/(x2-x1):
m = (y2-y1)/(x2-x1) = (2-6)/(-6 - -6) = -4/0
The denominator has a zero, so it is undefined.
Since the point-slope form requires "m" to be defined, you can't write the equation of the line using point-slope form.
Area of one blade is
A=(1/2)b*h=(1/2)7*4=28/2=14
for four blades
14*4=56
