Holden's current master bedroom is 309 sq ft and his master bath is 150 sq ft.  If he wants to add a home office/personal gym divided space that is twice as large as his bedroom and bathroom, how much sq ft will this new room have?
##Solution## His bedroom is 309 sq ft and his bathroom is 150 sq ft so these two rooms are 309+150 = <<309+150=459>>459 sq ft
He wants the new room to be twice as large as his bedroom/bathroom that is 459 sq so the new room is 2*459 = <<2*459=918>>918 sq ft
#### 918
