Answer 2

Calculating Paint Usage for the Rooms

The first step is to calculate the total floor area of the rooms and then determine the amount of paint needed to cover that area.

The first room has a length of 6 meters and a width of 5 meters, while the second room has a length of 5 meters and a width of 4 meters.

To find the total floor area of each room, we use the formula: Total Area = Length × Width

For the first room: Total Area = 6m × 5m = 30 square meters

For the second room: Total Area = 5m × 4m = 20 square meters

Now, to calculate the amount of paint needed for 1 square meter of floor, we can use the given data from the table.

According to the table, the amount of paint needed for 1 square meter of floor is 0.2 grams.

Therefore, to find the total amount of paint needed for each room, we can use the following formula: Total Paint Needed = Total Area × Amount of Paint per Square Meter

For the first room: Total Paint Needed = 30 square meters × 0.2 grams = 6 grams

For the second room: Total Paint Needed = 20 square meters × 0.2 grams = 4 grams

So, the total amount of paint needed to cover the floors in these two rooms is 6 grams for the first room and 4 grams for the second room.

Additional Problems

We can also create and solve additional problems based on the given data.

For example: 1. If a room has an area of 16 square meters, how much paint is needed to cover its floor? 2. If another room has an area of 24 square meters, how much paint is needed to cover its floor? 3. If a third room has an area of 19 square meters, how much paint is needed to cover its floor?

We can use the same formula to solve these problems: Total Paint Needed = Total Area × Amount of Paint per Square Meter

By substituting the given areas into the formula, we can calculate the amount of paint needed for each room.
