<span>The product of 7 and 0.04 is 0.28=true</span>
Step-by-step explanation:
Let
width,w
length, l = 1.6w ...eqn 1
area, a = l × w ...eqn 2
subst for l in eqn 2
a = 1.6 w × w = 4000
4000 = 1.6 w^2
w^2 = 2500
w = 50
subst for w in eqn 1
l = 50 x 1.6 = 80
length = 80 yds
width = 50 yds
I do believe that it's one of the bisected ones. bisect is the line that splits the middle and D is definitely wrong. So that should narrow it down. So I would go with A or B. Sorry if I didn't help much but it's better than having no clue.
