If Brian’s brother took the boys to the mall at 11:30 AM and left at 1:45 PM, how much time did the boys spend at the mall?

2  hours 15  minutes

Step-by-step explanation: 45 - 30 is 15 so now you just have to subtract the hours and since 11:00 only goes to 12 you would go to one after that so 1:00 is like 13 so 11 - 13= 2 so your answer is 1 hours and 15 minutes

2 hours and 15 minutes.

Step-by-step explanation:

Add 30 to 11:30 to 12:00. Add 45 to that to get 1 hour and 15 minutes. Then add the other hour.

just take the area of the square and then the area of the circle then subtract the circle area from the squares area
