Hi, First statement basically says us there is not a single ball with white color and even number painted on it.

Let's assume a side has length X. And difference in length between 2 side is 200 means another side will be X+200.
simply X+X+200 = 280 which leads to X = 40.
Area = 40 * (40+200)
Don't you think this is more easier one.... 
May be as beny told 200-

Let's assume length of one side is X, thus ractanguler has 2 sides of length X and another 2 sides of length 280-X... Now Area of ract. = X(280-X) = 280X - X^2.....(1) Diagonal will create 2 trinagle with hyotenuse of length 200... Using pythagora will get following equation, X^2 + (280-X)^2 = 200^2...

In fact according to D it's either X=1 or Y=0....
Now if we put only Y=0..equation comes to Z=XZ....
this can't be true since X can hold any value....it means D can't be answer at any cost....
