Step-by-step explanation:
We know that area of Trapezium =
1/2 * (16+48) * 20
= 640 m²
Now, for semicircle,
1/2 * pi * r²
= 1/2 * 3.14 * 18.86 * 18.86
= 558.44 m²
Adding both,
1198.44 m² ~ 2000 m²
Hope it helps :)
The correct answer is C. y> 1
The table of values to represent the relationship between the number of days and the number of puzzles she has completed will be:

2. 8
3. 12
4. 16
5. 20
<h3 /><h3>How to illustrate the information?</h3>
From the information, Maddie is determind to finish some extra credit math homework by completeing 4 math puzzles each day.
Therefore, the first day, she will do 4 puzzles. The second day will be:
= 2 × 4 = 8 puzzles
Third day = 3 × 4 = 12 puzzles.
In this case, the method that was used is simply to multiply the number of days by 4 since he does 4 puzzles everyday.
It should be noted that this illustrates a proportional relationship
