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

In a grid of A x B squares, the formula to find how many unique rectangles there are (and all squares are considered to be rectangles) is: A * (A+1) * B * ((B+1)/4) A and B are interchangeable. So in a 5 x 4 grid, there are 5 * (5+1) * 4 * ((4+1)/4) Or 5 * 6 * 4 * (5/4) Or 150 unique rectangles. Now if we switch A and B, the equation reads: 4 * (4+1) * 5 * ((5+1)/4) Or 4 * 5 * 5 * (6/4) Again 150 unique rectangles.

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.
