Question
The perimeter of a rectangle of length 2(x + 6) cm and
breadth 2(x + 5) cm is double the perimeter of a square of area 361 cm². Find the area of the rectangle.Solution
 Area of square = 361 cm²  Side of square = √361 = 19 cm  Perimeter of square = 19 × 4 = 76 cm  So, perimeter of rectangle = 2 × 76 = 152 cm  ⇒ 2(2(x + 6) + 2(x + 5)) = 152  ⇒ 4x + 22 = 76  ⇒ 4x = 54  ⇒ x = 13.5  So, length of rectangle = 2(13.5 + 6) = 39 cm  And, breadth of rectangle = 2(13.5 + 5) = 37 cm  Therefore, area of rectangle = 39 × 37 = 1443 cm2
