Question
The perimeter of a rectangle is
64 meters, and the ratio of its length to its breadth is 9:7. What is the area of the rectangle?Solution
ATQ, Let the length and breadth of the rectangle be 9p metres and 7p metres Then, perimeter of the rectangle = 2 × (length + breadth) = 2 × (9p + 7p) = 64 Or, 32p = 64 So, p = (64/32) = 2 Therefore, area of the rectangle = length × breadth = 9p × 7p = 18 × 14 = 252 m2
