Divide the rectangles by tens and ones for each factor. Find the number of squares in each smaller square. Then add the numbers of the squares in the four rectangles :
200+40+40+8=288
So, 12x24 =288
To divide the rectangle by tens and ones for each factor, you need to break down the dimensions of the rectangle. In this case, we have a rectangle with dimensions 12x24.
To divide 12 by tens and ones, we can see that the tens digit is 1 and the ones digit is 2. So, we divide it into a 10x2 rectangle and a 2x2 square.
To divide 24 by tens and ones, we can see that the tens digit is 2 and the ones digit is 4. So, we divide it into a 20x4 rectangle and a 4x4 square.
Now, let's find the number of squares in each smaller square:
For the 10x2 rectangle, there are 10 squares in each row, and 2 rows. So, the total number of squares in the 10x2 rectangle is 10x2 = 20.
For the 2x2 square, there are 2 squares in each row, and 2 rows. So, the total number of squares in the 2x2 square is 2x2 = 4.
For the 20x4 rectangle, there are 20 squares in each row, and 4 rows. So, the total number of squares in the 20x4 rectangle is 20x4 = 80.
For the 4x4 square, there are 4 squares in each row, and 4 rows. So, the total number of squares in the 4x4 square is 4x4 = 16.
Now, let's add the numbers of the squares in the four rectangles:
20 + 4 + 80 + 16 = 120.
Therefore, the total number of squares in the rectangles is 120.
Therefore, the equation 12x24 equals 288 is incorrect. The correct equation is:
12x24 = 120
