Area = length x height.
16 x 8 = 128
128 divided by 6 which is 21.3
I am not sure if this is right but please try to see if you will get it correct.
Step-by-step explanation:
from which text book please
Let X = tree height.
X/146 = 5.6/11.2
First let's define vertex: A point on the curve with a local minimum or maximum of curvature. If we look for the minimum and maximum value of the equation y=x^2+5: minimum value X=0, substitute in the equation to get the maximum value of Y y = 0^2 + 5y = 0 + 5y= 5 so the ordered pair is (0,5) Hope That Helped =D
