13 +40 = 53.

8/40 + 5/40 = 13/40
Area = Length*Width so Width = Area/Length = 40/[10+sqrt(13)] = 40*[10-sqrt(13)] / [10+sqrt(13)][10-sqrt(13)]= [400 - 40*sqrt(13)] / [100 - 13]= 400/87 - 40*sqrt(13)/87= 40/87*[10 - sqrt(13)]= 2.94 approx.
this equals 818
50 + 40 + 40 + 40 + 30 + 30 + 20 + 10 = 260

1/5 + 1/8 = 8/40 + 5/40 = 13/40
Area = Length*Width so Width = Area/Length = 40/[10+sqrt(13)] = 40*[10-sqrt(13)] / [10+sqrt(13)][10-sqrt(13)]= [400 - 40*sqrt(13)] / [100 - 13]= 400/87 - 40*sqrt(13)/87= 40/87*[10 - sqrt(13)]= 2.94 approx.

13/56 + 40/56 = 53/56
36 + 35 + 40 + 40 + 40 + 40 + 40 = 271 271 is the answer
2/8 + 2/5 = 10/40 + 16/40 = 26/40 = 13/20
1/5 + 1/8 = 8/40 + 5/40 = 13/40
