The parameter of a square is double the perimeter of a rectangle. The area of the rectangle is 480 sq cm. Find the area of the square. Choose one:
A) 200 sq cm
B) 72 sq cm
C) 162 sq cm
D) Cannot be determined
E) None of these
Let the side of the square be a cm. Let the length and the breadth of the rectangle be l cm and b cm respectively.   4a = 2(l + b)   2a = l + b   l . b = 480   We cannot find ( l + b) only with the help of l . b. Therefore a cannot be found .   Area of the square cannot be found.   ANSWER:Cannot be determined
