Please reason step by step, and put your final answer within \boxed{}.
A rectangular wall is covered entirely with three kinds of decorative tiles: small, regular, and jumbo. The small tiles have a length-to-width ratio of 2:1, while the regular and jumbo tiles have the same length-to-width ratio of 3:1. The wall consists of 2/5 small tiles, 3/10 regular tiles, and 1/4 jumbo tiles. Jumbo tiles have a length three times that of regular tiles. If regular tiles cover 90 square feet of the wall, and no tiles overlap, what is the area of the entire wall?
