Question

2. 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 m^2.

Answer 1

Hence the total cost of developing a garden is around Rs. 17,875.

Explanation:

Side of the square plot = 25 m

Formula: Area of the square plot = square of the side = (side)2

= (25)2 = 625

Therefore the area of the square plot is 625 m2

Length of the house = 20 m and

The breadth of the house = 15 m

Area of the house = length×breadth

= 20×15 = 300 m2

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

= 625–300 = 325 m2

∵ The cost of developing the garden per sq. m is Rs. 55

The cost of developing the garden 325 sq. m = Rs. 55×325

= Rs. 17,875

Hence the total cost of developing a garden is around Rs. 17,875.
