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.

Answer 2

area of the garden = area of the square plot - area of the house

Side of square plot = square x square

= 25 x 25

= 625 m sq.

area of the house = lxb

lenght = 20m

breadth = 15m

area of the house = 20 x 15

= 300m sq.

area of the garden = 625 m sq. - 300m sq.

= 325m sq.

Cost of developing garden = Rs.55 x 325m sq.

= Rs. 17,875
