How to print number of rectangles in N * m grid?
We are given a N*M grid, print the number of rectangles in it. Input : N = 2, M = 2 Output : 9 There are 4 rectangles of size 1 x 1. There are 2 rectangles of size 1 x 2 There are 2 rectangles of size 2 x 1 There is one rectangle of size 2 x 2.
How many rectangles are in a 600×400 image?
240000 rectangles. The image is 600×400 pixels, and since squares are a kind of rectangle, I’m going to go with that. I’m thinking its going to be more complex than that though.
How many rectangles are there in a 1×1 grid?
If the grid is 1×1, there is 1 rectangle. If the grid is 2×1, there will be 2 + 1 = 3 rectangles If it grid is 3×1, there will be 3 + 2 + 1 = 6 rectangles. we can say that for N*1 there will be N + (N-1) + (n-2) … + 1 = (N) (N+1)/2 rectangles.
