HELP ME 30 POINTS GEOMETRY

I think it is 0.38

Step-by-step explanation:

12+14=26

26+12=38

38 as a decimal is equal to 0.38

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
