The complete question in the attached figure
Let
x-------> represent the length side of the original square patio
we know that
Area of the original square patio=x²
x=9 ft
Area=9*9---------> 81 ft²
if Ezra <span>reduce the width by 4 feet and increase the length by 4 feet
</span>then
the new dimensions are
(x+4) ft x (x-4) ft
Area of the new patio=(x+4)*(x-4)----> (9+4)*(9-4)----> 13*5---> 65 ft²
therefore
the answer is the option
<span>A. lw = (x + 4)(x – 4); 65 square feet</span>
