What is the surface area?

482.5

Step-by-step explanation: 195.0 + 180.0 + 32.5 + 75.0 = 482.5

linear pair postulates

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
