Maria has a square brick patio. She wants to reduce the width by 3 feet and increase the length by 3 feet. Let x represent the length of one side of the square patio. Write expressions for the length and width of the new patio. Then find the area of the new patio if the original patio measures 8 feet by 8 feet.
a. lw= x (x-3); 40 square feet
b. lw= (x+3) (x-3); 53); 55 square feet
c. lw= (x+3) (x+3); 121 square feet
d. lw= (x-3) (x-3); 25 square feet
