The ratio of length to breadth of a rectangle is 10:13.
If the sum of the length and breadth of the rectangle is 92 cm, then find the area (cm2) of the rectangle.Solution
Let the length and breadth of the rectangle be 10x cm and 13x cm, respectively. According to the question, 10x + 13x = 92 Or, x = 92/23 = 4 Therefore, area of the rectangle = 10x × 13x = 130x2 = 2080 cm2
