Question: The perimeter of a square-shaped piece of paper is 20 cm shorter than the height of a computer screen. How many cm is the height of the screen if the side of the square paper is 20 cm?
Answer: The perimeter of a square is found by 4 * side, which means the square paper has a perimeter of 4 * 20 = 80. Since the perimeter of the square is 20 cm shorter than the height of the computer screen, the height of the computer screen is 20 + 80 = 100cm. The answer is 100.
[Question]Holden's current master bedroom is 309 sq ft and his master bath is 150 sq ft. If he wants to add a home office/personal gym divided space that is twice as large as his bedroom and bathroom, how much sq ft will this new room have?
[Answer]His bedroom is 309 sq ft and his bathroom is 150 sq ft so these two rooms are 309 + 150 = 459 sq ft. He wants the new room to be twice as large as his bedroom / bathroom that is 459 sq so the new room is 2 * 459 = 918 sq ft. The answer is 918.
Q: Jennifer wants to go to a museum. There is one 5 miles away from her home and one 15 miles away. If Jennifer goes to both museums on two separate days, how many miles total will she travel?
A: Jennifer's home is 5 miles away from the first museum, so the round trip back and forth is 5 miles there + 5 miles back = 10 miles altogether. On another day Jennifer goes to a museum 15 miles away + 15 miles to return home = 30 miles total. Combined, Jennifer travels 10 miles on the first day + 30 miles on the second day = 40 miles Jennifer travels total. The answer is 40.
Question: Samir just turned half the age Hania was 10 years ago. If in five years Hania will be 45 years old, what will Samir's age be five years from now?
Answer: If in five years, Hania will be 45 years old, currently she is 45 - 5 = 40 years old. Ten years ago, Hania was 40 - 10 = 30 years old. Samir just turned half the age Hania was 10 years ago, which means she is 30 / 2 = 15 years old. In five years, Samir will be 15 + 5 = 20 years old. The answer is 20.

[Question]Jim spends 8 hours scuba diving. In that time he finds a treasure chest with 100 gold coins in it. He also finds 2 smaller bags that have half as much gold each. How much gold does he find per hour?
