The correct sum is 57.
To find the sum of 29 + 28 using tiles, follow these steps:
1. Start with 29 tiles.
2. Add 28 tiles.
3. Count the total number of tiles.
4. The sum of 29 + 28 using tiles is 57.
Therefore, the correct answer is 57.
To find the sum of 29 + 28, you can use tiles to visually represent the numbers. Each tile will represent one unit.
For 29, you would use 2 tiles to represent the digit 2 in the tens place and 9 tiles to represent the digit 9 in the ones place.
For 28, you would use 2 tiles to represent the digit 2 in the tens place and 8 tiles to represent the digit 8 in the ones place.
Now, you can combine the tiles from both numbers.
In the tens place, there are 2 tiles from 29 and 2 tiles from 28, which makes a total of 4 tiles.
In the ones place, there are 9 tiles from 29 and 8 tiles from 28, which makes a total of 17 tiles.
Therefore, the sum of 29 + 28 is 44 (4 tens and 4 ones), which is not one of the options you provided.
