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:

17875 Rs.

Step-by-step explanation:

Area of square - area of rectangular section for house = area of the garden

25 x 25 - 20 x 15 =

625 - 300 = 325

325 m^2 x 55(Cost of garden development) = 17875

Answer 2

Given Data :

• Side of the plot = 15 m
• Length of the house = 20 m
• Breadth of the house = 15 m

To Find :

• Total cost of developing garden around the house at the rate of ₹55 per m²

Solution :

• Calculating the areas of the square plot and the rectangle house region.

Area of the square = Square of its sides.

➞ Area = (s)²

➞ Area = (25)²

➞ Area = 625 m²

Rectangle Area = Product of Length & Breadth

➞ Area = (L × B)

➞ Area = (20 × 15)

➞ Area = 300 m²

• Calculating Area of the garden and the required cost.

Area of garden = (Area of square plot side 25 cm) – (Area of the rectangular house)

➞ Area of garden = 625 m² – 300 m²

Cost of developing garden per m² = Rs. 55

Cost of developing garden 325 m² = (325 × 55)

➞ Rs. 17, 875

Hence, Required cost of developing the garden is Rs. 17, 875.
