Question

painting measures 2.4 feet from left to right. It’s hung in the center of a rectangular wall measuring 20 feet from left to right. What is the distance between the right edge of the painting and the right edge of the wall? Assume that the painting does not tilt

Answer 1

8.8, you do 20-2.4, then divide that sum

Answer 2

The distance of the right edge of the painting and the right edge of the wall is 8.8 feet.

Explanation:

The length of the painting (Art work) is 2.4 feet from left to right.

The wall measures 20 feet from left to right.

Since the painting is hung at the center of the given wall, thus the distance of the right edge of the painting and the right edge of the wall = the distance of the left edge of the painting and the left edge of the wall.

The distance of the right edge of the painting and the right edge of the wall

=
`(length of wall - length of painting)/(2)`

=
`(20 - 2.4)/(2)`

=
`(17.6)/(2)`

= 8.8

The distance of the right edge of the painting and the right edge of the wall is 8.8 feet.
