A furniture store is selling a sofa, love seat, and chair. Including armrests the sofa width is 220 in and the width os the love seat is 160 in. Find width of chair.
It depends on how big the chair is. How do you know that the chair seat is the same width as the sofa seats? You need more information.
Here is a guess....
Sofa seats 3 (?) love seat allows for 2
220 - 160 = 60 inches
Love seat sits 2 cahir sits 1
160 - 60 = 100 inches That is some rather LARGE furniture ! Couch is over 18 feet long !
