Melissa is creating a geometric design using similar rectangles. One of her rectangles is 2 inches wide and 6 inches long. She wants to have another rectangle that is 3 inches wide. To follow her design, how long must the second rectangle be?
Remember that
If two figures are similar, then the ratio of its corresponding sides is proportional
that means
3/2=x/6
solve for x
x=(3/2)*6
x=9 in
therefore
the length is 9 inches
