Question

Mrs. Kaushik has a square plot with the measurement as shown in the following figure. She wants to construct a house in the middle of the plot. A garden is developed around the house. Find the total cost of developing a garden around the house at the rate of Rs 55 per m².

Answer 1

Area of the square plot = (25 m)² = 625 m² Area of the house = (15 m) × (20 m) =300 m²

Area of the remaining portion = Area of square plot − Area of the house = 625 m² − 300 m² = 325 m²

The cost of developing the garden around the house is Rs 55 per m². Total cost of developing the garden of area 325 m² = Rs (55 × 325) = Rs 17,875
