Question :-

Mrs. Kaushik has a square plot with the measurements 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 RS.55 per metre square.

given :-

• Side of plot = 15 m

• Length of house = 20m

• Breadth of house = 15m

To find :-

• total cost of developing a garden around the house at the rate of RS.55 per metre square.

Solution :-

Area of the plot

$\: = side \times side$

$= 25m \times 25m$

$= 625 {m}^{2}$

Area of the house

$= l \times b$

$= 20m \times 15m$

$= 300 {m}^{2}$

_______________

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
