Answer 2

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 ${m}^{2}$

Given :-

• Side of plot = 25m

• length of house = 20m

• Breadth of house = 15m

To find :-

• total cost of developing a garden around the house at the rate of ₹ 55 per ${m}^{2}$

Solution :-

Area of the plot

⠀ ⠀= side × side

⠀⠀ = 25 m × 25 m

⠀ ⠀= 625${m}^{2}$

Area of the house

⠀ = l × b

⠀ = 20 m × 15 m

⠀ = 300${m}^{2}$

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 × 55

⠀ ⠀= ₹ 17875
