Question 1157114

Casey wants to shrink a poster at Kinko’s. The poster is two feet by three feet. He wants to make it 1/9 of the area of the original poster. What will be the dimensions in inches of the new poster?
<pre>Original dimensions of poster: 2' x 3', or 24" x 36"
Shrinking ORIGINAL AREA by {{{1/9}}} MEANS shrinking the DIMENSIONS by {{{sqrt(1/9)}}}, or by {{{1/3}}}.
Shrinkage results in ORIGINAL DIMENSIONS of {{{highlight_green(matrix(1,17, 24, by, 36, being, SHRUNK, to, (1/3), of, "24", "=", highlight(matrix(1,2, 8, inches)), by, (1/3), of, "36", "=", highlight(matrix(1,2, 12, inches))))}}}
