### Question Description

The area of a projected picture on a movie screen varies directly as the square of the distance from the projector to the screen. If a distance of 20 feet produces a picture with an area of 6**[c]** square feet, what distance produces an area of 1**[a]**0 square feet? Round to the nearest tenth of a foot.

Note: if **[a]**=2, then 1**[a]**0=120 feet, and if **[c]**=8, then 6**[c]**=68 feet
