How many rectangles in a 4 by 4 square?

Answer 1

Oh, dude, like, there are 10 rectangles in a 4 by 4 square. You got your big rectangle, then you got 4 rectangles that are 3 by 2, and then you got 5 little 1 by 1 squares. So, yeah, that's like 10 rectangles in total.

Answer 2

To determine the number of rectangles in a 4 by 4 square, we can use the formula for the number of rectangles in an n by m grid, which is (n*(n+1)m(m+1))/4. In this case, n = 4 and m = 4, so the number of rectangles would be (4*(4+1)4(4+1))/4 = 40 rectangles. This includes all possible rectangles of different sizes that can be formed within the 4 by 4 square.

Answer 3

100

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
