Question

Mrs. Kaushik has a square plot with the measurement as shown in the 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 ₹ 55 per m².

Answer 1

Answer: Side of a square plot = 25 m

Therefore, Area of the house = length x breadth = 20 x 15 = 300 m² 

Area of garden = Area of square plot – Area of house = 625 – 300 = 325 m² 

Cost of developing the garden per sq. m = ₹ 55 

Therefore, Cost of developing the garden 325 sq. m = ₹ 55 x 325 = ₹ 17,875 

Hence total cost of developing a garden around is ₹ 17,875.
