Grade 12Algebra
A rectangle with sides 2m-1 and 2n-1 is divided into squares of unit length by drawing parallel lines .Then the number of rectangles possible with odd side lengths is;
a) (m+n-1)^2
b)4^(m+n-1)
c)m^2 * n^2
d)m(m+1)n(n+1)
sorry for image not being there in question..the question is from iit 2005
