@Brij,vinay (4,4) is square - 11 years agoHelpfull: Yes(4) No(5)
- 2L + 2B = L*B
L( B - 2 ) = 2B
L = 2B / (B - 2)
=> (L , B ) = (6 , 1) , (4 , 4) , (3 , 6) - 11 years agoHelpfull: Yes(3) No(13)
- all squares are rectangles..but all rectangles are not square so (4,4) is correct
and (6,3)and(3,6) - 11 years agoHelpfull: Yes(2) No(0)
