A rectangle has a width of 10 in and a length of 12 in. A similar rectangle has a width of 15 in. What is the length of the similar rectangle?

asked by Lana
  1. The lengths of both edges in similar rectangles have equal ratios.

    => (Length 1)/(Length 2) = (Width 1)/(Width 2)
    => 12/x = 10/15
    => x = (12*15)/10

    Solve for x.
