Shyanne Wheeler · Answer 1

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

Alessandra Perkins · Answer 2

48 = (2L+2W)

when increased in scale,

both sides are multiplied by the factor which is 1.5.

72 = 1.5 (2L+2W)
