@phi can you chick this, whenever your online!

Answer 3

the photocopy is the same size as the original (one presumes)
and side GH is the same length as CD

so you have to find CD

when they way the ratios of the two sides is 2:3
that means that the two sides are 2x and 3x where x is some "scale factor"
in this case, the sum of the 4 sides will be 18+2x+3x = 18+5x
and that equals the perimeter:
5x+18= 58

solve for x, and then find CD which has length 2x
