The length of a rectangle exceeds its breadth by 7 ems. If the length is decreased by 4 cm. and the breadth is increased by 3 cms., then the area of the new rectangle will be the same as the area of the original rectangle. What will be the perimeter of the original rectangle?

• 50 cms.
  If breadth(in cm.) of original rectangle=x, then length=x+7
  Given (x+7-4)(x+3)=(x+7)*x, x=9
  original rectangle's breadth=9,length=9+7=16,
  So perimeter=2(16+9)= 50 cms.
