The relationship of arcs is:
S '/ S = ((2/5) * pi * r) / (2 * pi * r)
Rewriting we have:
S '/ S = ((2/5)) / (2)
S '/ S = 2/10
S '/ S = 1/5
Therefore, the area of the shaded region is:
A '= (S' / S) * A
Where A: area of the complete circle:
A '= (1/5) * 100 * pi
A '= 20 * pi
Answer:
The area of the shaded region is:
A '= 20 * pi
800mp 1h
1600mp 2h
3600mp 4h
7200mp 6h
6*2 = 12h

The width of the pool is 10 feet.
<h3>What is area of rectangle?</h3>
The area of rectangle is product of length and breadth.
Let the width be x.
length = 24 + 2x. and breadth = 12 + 2x
We know, area= 1408 ft².
(12 + 2x)(24 + 2x) = 1408
12*24 + 12*2x + 24*2x + (2x)² = 1408
288 + 72x + 4x² = 1408
4x² + 72x + 288 - 1408 = 0
4x² + 72x - 1120 = 0
x² + 18x - 280 = 0
x² - 10x + 28x - 280 = 0
x(x - 10) + 28(x - 10) = 0
(x - 10)(x + 28) = 0
So, x=10, -28.
Hence, the width be 10 feet.
