Question
The perimeter of a rectangle is 68 cm more than its
length. If the length and breadth of the rectangle are in the ratio 7:5, respectively, then find the area of the given rectangle.Solution
Let the length and breadth of the rectangle be '7x' cm and '5x' cm, respectively. ATQ; 68 + 7x = 2 X (7x + 5x) Or, 68 + 7x = 24x Or, 68 = 17x So, x = 4 So, area of the rectangle = (7 X 4) X (5 X 4) = 560 cm2
