Question

A 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 the painting does not tilt

Answer 1

2.1 feet. If you take the middle of the wall it would be 10 feet. Take the 4.2 which equals 4.2,feet on each side.1/2 of the picture is 2.1.

Answer 2

If the painting lies in the middle of the rectangle and half of 20 f is 10  so then half of the painting that is on half of the wall would be only 1.2f if you take 10-1.2= 8.8f your final answer.
