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.
The answer is 10.8. You turn 10 4/5 into 54/5. Then you divide 54 by 5.
