Find the sides by figuring out what makes sense I got two 19ft sides and two 5ft sides
So 19*1.5 is 28.5 so now you have two 28.5ft
Then 1.5*5 is 7.5 now you have two 7.5ft sides
28.5+28.5+7.5+7.5=72ft which is the new perimeter

48=(2L+2W)

when increased in scale,
both sides are multiplied by the factor which is 1.5.
72 =1.5(2L+2W)
