Its a simple maths pnc question we use to do in class 11th
the total number of rectangle possible and (((n+1)*(n))/2 )*(((m+1)*(m))/2);
now u have to subtract the rectangle having (n,m) cell which will be nothing but n * m;
so just subtract the n*m from the total number of rectangles.
```

Itâ€™s showing partial_correct.
