Answer:
10.92 m
Step-by-step explanation:
To solve for the height, we first find the area of the triangle. Since the area of a triangle is 1/2 of the base times the height, we get the area to be 109.2. Dividing it by 20 and then multiplying by 2, we get 10.92 as the height.
Yes the quotient of 9 is rational

, and
. Subtracting this from the numerator gives a remainder of

, and
. Subtracting this from the previous remainder gives a new remainder of

is not a multiple of
, so we're done. Then
