Let's assume
length of box is l
width of box is w
we know that
area of rectangle = length*width
...................(1)
now, we are given
fencing length is 20 foot
fencing length will be equal to perimeter
and we know that
so, we get
now, we can solve for l
now, we can plug that in first equation
now, we can solve for w
now, we can find length
or
so, option-B..................Answer
