The figures shown are similar. what is the scale factor? a. 1/9 b. 3/7 c. 4/7 d. 6/7

C. 4/7

Step-by-step explanation:

The scale factor is the ratio of corresponding side lengths (the only ones marked with a length).

... 12/21 = 4·3/(7·3) = 4/7

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
