Let the breadth of the rectangle = x mso, length of the rectangle = x+20 mNow, perimeter = 280 m⇒2length+breadth = 280⇒x+20+x = 140⇒2x = 120⇒x = 60So, breadth = 60 mlength = 60 + 20 = 80 m

The length of a rectangular field is 20 m more than its breadth. If the perimeter of the field is 280 m, what is its length?
