Answer:
D. (25π - 50) sq m
Step-by-step explanation:
Since ABCD is a square with the area of 100, we know that the dimensions are 10 by 10. With that, we can find that triangle ABC = 50 sq m because of (h*l)/2. Since A is the center of the circle that contains arc BD, we know that 10 is the radius of the quarter-circle ABC. Using (πr^2)/4 to get the area of the quarter-circle, we get that the quarter-circle ABC = 25π sq m. But the original triangle ABC in the quarter-circle is not shaded. Therefore, we subtract 50 from 25π, which leads to (25π - 50) sq m.

Step-by-step explanation:
Answer:
False.
Step-by-step explanation:
1. 0.2 is 1 percent of 20.
2. 0.2x20 is 4
3. 14 divided by 0.2 is 70, that means 14 is 70% of 20.
4. Therefore, 4 is 20% of twenty.
