Does rectangle A have a greater perimeter that rectangle B?
1) The length of a side of rectangle A is twice the length of a side of rectangle B.
2) The area of rectangle A is twice the area of rectangle B.
Answer is B
Let a and b be the sides of rectangle 1; x and y the corresponding sides of rectangle 2.
Perimeter is defined as 2*(a+b) for Rect 1 and 2*(x+y) for Rect 2
From (1) we only know that a=2x. This does not help us answer our question since the other side is unknown
(2) tells us that atleast one of the sides of Rect A is larger than the lenghts of the sides on Rect B. This means that the perimeter of A would be larger than the perimeter of B
Hence answer is B
