Oh, what a delightful question! In a 5 by 4 grid, you can find a total of 30 rectangles. Each row and column adds to the total count, and then you have to consider larger rectangles made up of multiple rows and columns. Just imagine all those happy little rectangles coming together to create a beautiful 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.
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.
A 4 x 5 grid has 150 rectangles because -
Formula: (n + all natural numbers before n) * (m + all natural numbers before m)
(4 + 1 + 2 + 3) * (5 + 1 + 2 + 3 + 4)
= 10 * 15
= 150
