# 2.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 $$m^2$$.

We have the area of the square plot =$$side \times side = 25 m \times 25 m = 625 m^2$$
Area of the rectangular house =$$l \times b = 20 m \times 15 m = 300 m^2$$
Therefore, Area of the garden to be developed = Area of the plot – Area of the house = $$625 m^2 – 300 m^2 = 325 m^2$$
Cost of developing the garden = $$₹ 325 \times 55 = ₹ 17875$$
