Answer 1

Answer:

Step-by-step explanation:

side of a square plot = 25 m

area = side×side

= 25m×25m

= 625 m²

length of house = 20m

breadth of house = 15m

area= l×b

= 20m× 15m

= 300m²

therefore,area of garden = area of plot - area of house

= 625m² - 300m²

= 325m²

Cost of developing 1m² of garden = Rs 55

therefore,cost of developing 325m² of garden = ₹55×325

= ₹ 17,875
