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:

As per the given data, first we need to find the whole area and then subtract the area occupied by the house.

Area of the square plot =25 m×25 m=625 m  

2

 

Now, total area = area occupied by the house = Area of rectangle with length 20 m and breadth 15 m.

∴ Area of the house =20 m×15 m=300 m  

2

 

Then, area occupied by the garden = Total area − area of the house =625−300=325 m  

2

 

Cost for 1 m  

2

=Rs. 55

Then, total cost for developing a garden =325×55=Rs. 17875

Hence, the answer is 17875.

Step-by-step explanation:

Answer 2

Answer:-

17,875

Explanation:-

Area of plot=S×S

=25×25

=625m²

Area of house=L×B

=20×15

=300m²

Area of garden=Area of plot–Area of house

=625m²–300m²

=325m²

Cost of 1m²=₹55

Cost of 325m²=₹55×325

=₹17,875
