Question

A decorator hangs 8 pictures that each measure 1012 inches wide on a wall. They’re spaced 6 inches apart with 4 inches on each end, so that they fit perfectly on the wall. How wide is the wall?

Answer 1

did you draw a diagram to understand?

you have 4 inches on each side of the 1st and last painting

you have 6 inches of space between the 8 tables, so you have 7 spaces of 6 inches

each painting is 1012 inches wide

wall width:

4*2 + 7*6 + 1012*8 = 8146inches
