Question
If the perimeter of rectangle is 54 cm and its length is
3 cm more than breadth then find its area?Solution
According to the question Let the length and breadth of rectangle are x cm and (x – 3) cm respectively. Perimeter of rectangle = 2 x (Length + Breadth) ⇒ 2 (x + x – 3) = 54 ⇒ x = 15 Length = x = 15 cm Breadth = x – 3 = 12 cm Area of rectangle = Length x Breadth Area of rectangle = 15 x 12 = 180 cm² Â
