What is the perimeter of a parallelogram with sides of lengths x and y ?
(1) x = 10 - y
(2) x^2 + y^2 = 52
(1) x = 10 - y
(2) x^2 + y^2 = 52
IMO A
Perimeter of a ||gram is 2x+2y where x and y are the sides.
Statement 1 gives you x+y . So 20 is 2x+2y. Sufficient
Can't think of any way to factor statement 2. Insufficient
