.
L=length; W=breadth=1.3L; A=Area
LW=A
L%281.3L%29=A
1.3L%5E2=2080cm%5E2
L%5E2=1600
L=40cm
.
Side of square=1/2(length of rectangle)
side of square=1/2(L)
side of square=1/2(40cm)=20cm
.
Area_of_square=side%5E2
Area_of_square=%2820cm%29%5E2
Area_of_square=400cm%5E2
ANSWER: The area of the square is 400 square centimeters.
