The question is in the picture below!

1/3

Step-by-step explanation:

To find the scale factor, divide a dimension in the new figure by the corresponding dimension in the original figure.

Figure B is a scaled copy of Figure A, so Figure A is the original figure, and Figure B is the new figure.

The side measuring 5 in Figure B corresponds to the side measuring 15 in Figure A.

scale factor = (length in new figure)/(length in original figure)

scale factor = 5/15 = 1/3

i dont know

step-by-step explanation:

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
