34m
23m​

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.
