plz tell me a formula for finding squres in m*n grid

• for m*n
  
  no of square--- m*n+(m-1)*(n-1)... till either of (m-i) or (n-i) become 1.
  
  no of square +no of rectangle = m*(m+1)*n*(n+1)/4

• formula of m*n grid
  no. of sqr=(m-1)(n-1)+(m-2)(n-2)+............till (m-1)or(n-1)comes to 1
  no. of reactangle=(1+2+3+4.........m)(1+2+3+4............n)

• n(n+1)(2n+3t+1)/6
  here t=m-n
