Hope this helps! let me know if you need any further assistance!
L = 5+ 2W
LW= 250
you really only need 2 equations
but if you want you could also put
L+W = 35 cm
W= 10
L= 25
I would say 7 because if you divide 28\4 you get 7 and if you add 7 four times you get 28 for WY+XZ=28
1. This is a rule which helps a person identify if a number is divisible by nine.
There is no specific answer to why this is observed but I believe that is just how multiples of nine and three behave!
It is the same with the multiples of three as well!
By the way the 6 digit number could be 513315
thanks, hope that helps!!
