**Reiny**, Wednesday, December 28, 2011 at 8:32amMake a sketch,

let part A be x by y

let part B be x by 5

let part C be 5 by 5 , the square

then part D is 5 by y

xy : 5x : 25 = 10:18:5

so

xy/10 = 5x/18 = 25/5

using 5x/18 = 25/5

5x = 90

x = 18

then in xy/10 = 25/5

18y/10 = 5

y = 50/18 = 25/9

area of D = 5y = 5(25/9) = 125/9 or 13 8/9
