Hello!
First, since you read 50 pages in 1 hour, 50/2 = 25 pages in 1/2 hour.
Then, your sister read 40 pages in 1 hour, 40/2 = 20 pages in 1/2 hour.
Then we subtract: 25-20 = 5 pages.
So: You read 5 pages more than your sister in 1/2 hour.
Hope this helped! c:

Answer:
28.25
Step-by-step explanation:
just do 226 divided by 8
A = 3W² + W + 1/8πW²
rectangular window is L x W
semicircle is 1/2 πr²
r = 1/2 W
L = 3W + 1
A = W(3W + 1) + 1/2 π(1/2W)²
