Question
The cost of fencing a rectangular garden at Rs. 10/metre
is Rs. 1000. If the ratio of the length to breadth is 3:2, find the area of the garden.Solution
Let the length and breadth be 3x metres and 2x metres respectively.
According to the question,
2 × (3x + 2x) = 1000 / 10
Or, 2 × 5x = 100
Or, 10x = 100
Or, x = 10 metres
Therefore, area = 3x × 2x = 6x² = 6 × 100 = 600 m²
