Let the width be w.
Then the length = 2w + 11.
The area is w * l = w(2w + 11).
Now we can write an equation for the area as follows:
\(2w^{2}+11w=63\)
This equation can be rearranged to make the following quadratic:
\(2w^{2}+11w-63=0\)
The factors of the quadratic are:
(2w - 7)(w + 9) = 0
The positive solution is w = 3.5.
Plugging in this value for w into the equation for the length we get:
Length = 18 yards, width = 3.5 yards.
