Ho it can be D since we have nit given that sides will be integers

IMO correct answer should be C.

Looking forward for more responses.

Thanks

area of rect 1 is xy =100
area of rect 2 is xy + 5x

Now S1 says x=5
area of rect 2= xy + 5x = 100+50*5
Sufficient
NOW S2
y=20
xy=100, from this x=100/20 = 5
area of rect 2 = xy+5x, we know x and y
sufficient

Hence either statement alon s sufficient

i don't know why my approach, initially was to write: y=100/x...but we have already value for x...
this questions is very simple....
1. x=5 -> y=20. we can find x(y+5).
2. y=20 -> x=5. we can find x(y+5).

note that we need not find the value for x(y+5). we need only to answer the question - do we have sufficient information? the answer is YES for both statements.

D.

for just in case: x(y+5) = 5*25 = 125.
