YOU FIRST MUST REALIZE THE EQUATION FOR THE AREA OF A RECTANGLE. IT IS A=LW WHEN YOU UNDERSTAND THIS, THEN WE CAN PROCEED W/ YOUR MATH DILEMMA!!! THE LENGTH IS 4 TIMES THE WIDTH......SO LET X = THE WIDTH. THE EQUATION WILL THEN LOOK LIKE THIS : (4X)(X) = 48 ---->>>> 4X^2=48 ---->>>> X^2=12 ---->>>> X=3.4641016 ------>>>>> ROUNDING OFF X=3.5(APPROX) I HOPE THIS HELPS YOU!?
