13 x 1= 13 is an example of which property?

Identity property on multiplication

Step-by-step explanation:

If you multiply any number by 1, you will get the same number.

15 * 1 = 15   ; 25* 1 = 25

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
