Answer:This requires a couple of steps to solve: find the area of the square, find the area of the rectangle, and lastly finding the difference.
For the area of the square it is just the squaring the side length: A= s2
Asquare= (9 ft)2= 81 ft2
The area of the rectangle is the width times length: A=lw
Arectangle= 10 ft * 19 ft= 190 ft2
Now, to find the area of the region inside the rectangle that surrounds the square: Aregion= Arectangle-Asquare
A= 190 ft2-81 ft2= 109 ft2
if it doesn't answer youre question im sorry
