the sum of the length and breadth of the rectangle is 45 cm, then find the area (cm 2 ) of the rectangle.Solution
Let the length and breadth of the rectangle be 6x cm and 9x cm, respectively. According to the question, 6x + 9x = 45 Or x = 45/15 = 3 Therefore, area of the rectangle = 6 x× 9x = 54x2 = 486 cm2
