A rectangular region has a fence along three sides and a wall along the fourth side. The fenced side opposite the wall is twice the length of each of the other two fenced sides. If the area of the rectangular region is 200 square feet, what is the total length of the fence, in feet?  Options
A) 10 B) 20 C) 30 D) 40 E) 80
two sides EACH = x the third = 2x and the wall length is thus 2x too   x*2x = 2x^2 = 200 ie x^2 = 100 ie x = 10   L = 20 W=10   TOTAL LENGHT OF FENCE = 2*10 + 20=
