6. A rectangular garden is drawn with a length of 25 meters and a width of 15 meters. What is the perimeter of the garden? Answer: 80 Solution: We have a rectangular garden with length 25 meters and width 15 meters. We are asked to find the perimeter. Recall the formula for the perimeter of a rectangle.
   Full step-by-step solution

   Step 1: Understand the problem. We have a rectangular garden with length 25 meters and width 15 meters. We are asked to find the perimeter. Step 2: Recall the formula for the perimeter of a rectangle. Perimeter = 2 × (length + width) Step 3: Substitute the given values into the formula. Length = 25 m Width = 15 m Perimeter = 2 × (25 + 15) Step 4: Perform the addition inside the parentheses. 25 + 15 = 40 Step 5: Multiply by 2. 2 × 40 = 80 Step 6: State the final answer with units. The perimeter of the garden is 80 meters.

7. Lily's music class starts at 2:30 PM. The class lasts for 45 minutes. What time does Lily's music class end? Answer: 3:15 PM Solution: Start with the given time. Lily's class starts at 2:30 PM. Add the duration of the class.
   Full step-by-step solution

   Step 1: Start with the given time. Lily's class starts at 2:30 PM. Step 2: Add the duration of the class. The class lasts for 45 minutes. We add this to the start time. We can break the 45 minutes into two parts to make it easier: 30 minutes + 15 minutes. Step 3: Add the first 30 minutes. 2:30 PM + 30 minutes = 3:00 PM. (30 minutes after 2:30 is 3:00.) Step 4: Add the remaining minutes. We have added 30 minutes of the 45, so we still have 15 minutes left to add. 3:00 PM + 15 minutes = 3:15 PM. Step 5: State the final answer. Therefore, Lily's music class ends at 3:15 PM.

8. What time: 8:40 Answer: 8:40 Solution: The hour is 8, so the hour hand is between 8 and 9. The minutes are 40, which means 40 minutes past the hour. On a clock, each number represents 5 minutes.
   Full step-by-step solution

   Step 1: The hour is 8, so the hour hand is between 8 and 9. Step 2: The minutes are 40, which means 40 minutes past the hour. Step 3: On a clock, each number represents 5 minutes. 40 minutes is 8 groups of 5 minutes (8 × 5 = 40). Step 4: Count by fives around the clock: 5, 10, 15, 20, 25, 30, 35, 40. This means the minute hand points to the 8 on the clock. The time is 8:40.
