Question

Lucero wants to hang 3 paintings in her room. The widths of the paintings are 10 1/2 inches, 3 1/2 feet, 2 feet, and 2 3/4 inches. If she hangs them next to each other with 3 inches between them, what is the total width of the wall space she will need?

Answer 1

7 ft 1 1/4 in

Explanation:

The total width of 3 paintings and 2 spaces is ...

(10.5 in) + (3 in) + (3 ft 6 in) + (3 in) + (2 ft 2 3/4 in)

= (10.5 +3 +6 +3 +2.75) in + (3 +2) ft

= 25.25 in + 5 ft = 1.25 in + 24 in + 5 ft

= 7 ft 1 1/4 in

The total width of wall space needed for the paintings is 7 feet 1 1/4 inches.

_____

If two more 3-inch spaces are added, one on each end, then the total width is 7 feet 7 1/4 inches. The problem isn't clear about that, saying only that there are spaces between the paintings.
