Projected Picture
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
