10,10 and 20 cannot as 10+10=20 so there would be a triangle with no area.
The others can all be the sides of a triangle as 7+7>8, 7+6>11 and 2+8>9.

Answer:
Width is 3 ft
length is 6 ft
Step-by-step explanation:
Let x = the width
Let 2x = the length
Let h = the height
We know that volume is given v = l×b×h
so we have v = volume
surface area include 2 ends + 1 bottom and 2 sides excluding top
we have calculate
By graphing above equation we can calculate the value of x
Minimum S.A when x is 3 is the width so
2(3) = 6 is the length
