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 800 square feet, what is the total length of the fence, in feet? Choose the correct choice from the following.
A) 40  B) 80  C) 100  D) 120  E) 200
two sides EACH = x the third = 2x and the wall length is thus 2x too   x*2x = 2x^2 = 800 ie x^2 = 400 ie x = 20   L = 40 W= 20   TOTAL LENGTH OF FENCE = 2*20+ 40=
