A Grand Total of: 100 squares and rectangles.
OR: A rectangle is formed by 2 horizontal lines and 2 vertical lines. There are 5 horizontal and 5 vertical lines so the number of rectangles is 5C2 * 5C2 = 10 * 10 = 100

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 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.
12 squares.
You need 4 rectangles and two squares * * * * * No, you do not need to have squares: there can be six rectangles - as in a brick shape.

There are 4 squares in a 2 x 2 grid.
All squares are rectangles, but not all rectangles are squares. The definition of a rectangle is a 4 sided figure with 4 right angles. So all squares are rectangles.
