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 Rs 55 per meter square

Answer 1

Area of Garden = Total area of plot - Area of house

Total area of plot = 25 m x 25 m
( Side x Side )
= 625 m2

Area of house = 15 m x 20 m
( Length x Breadth )
= 300 m2

Area of garden = 625 - 300 = 425 m 2
Cost = 425 x 55
= 23,375 Rs ANS !

Answer 2

Answer:

Side of a square plot = 25 m

So, Area of square plot = (side)^2 = (25)^2 = 25 * 25 = 625 m^2

Length of the house = 20 m and

Breadth of the house = 15 m

So, Area of the house = length * breadth = 20 * 15 = 300 m^2

Area of garden = Area of square plot – Area of house

                           = 625 – 300 = 325 m^2

Cost of developing the garden per sq. m = Rs55

So, cost of developing the garden 325 sq. m = Rs55 * 325 = Rs17,875

Hence total cost of developing a garden around is Rs17,875.
