Well, honey, in a 4 x 6 grid, you've got a total of 30 rectangles. You've got your 24 smaller rectangles formed by the individual squares, then you add 4 rectangles formed by 2 x 2 squares, and finally, you top it off with 2 rectangles formed by 3 x 2 squares. So, grab a calculator if you need to, but that's the tea!

To determine the number of rectangles in a 3 by 4 grid, we can use the formula for calculating the number of rectangles in an n by m grid, which is (n*(n+1)m(m+1))/4. Plugging in the values for a 3 by 4 grid, we get (3*(3+1)4(4+1))/4 = 30 rectangles. This includes rectangles of different sizes, such as 3x1, 2x2, and 1x3, within the grid.
In a 4 by 4 grid, there are 16 squares (1x1 squares), 9 rectangles that are 2x1, 6 rectangles that are 3x1, 4 rectangles that are 2x2, and 1 rectangle that is 4x4. Therefore, in total, there are 16 squares and 20 rectangles in a 4 by 4 grid.
To calculate the number of rectangles in a 5 by 4 grid, you can use the formula for the number of rectangles in an n by m grid, which is n*(n+1)m(m+1)/4. Plugging in the values for n=5 and m=4, you get 5*(5+1)4(4+1)/4 = 564*5/4 = 600/4 = 150 rectangles. So, there are a total of 150 rectangles in a 5 by 4 grid.
