Question

Miss Kaushal has a square plot with the measurement as shown in the. 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? 60 per m².​

Answer 1

Analysis:

In this question, we first have to find the total area of the plot and then subtract the area of the house from it. This will give us the area of the garden. When we multiply the area of the rate of developing the garden, we will get the total cost.

The Square Plot:

Side, a = 40 m

Area of a square = a²

Area of the plot = 40 x 40

= 1600 m²

The House:

Length = 30 m

Breadth = 25 m

Area of a rectangle = lb

Area of the house = 30 x 25

= 750 m²

The Garden:

Area of the garden = 1600 - 750 m²

Area of garden = 850 m²

The Cost:

Cost of developing a garden in 1 m² = Rs. 60

Total cost of developing the garden of area 850 m² = 850 x 60

= Rs 51000

The cost of developing a garden of area 850 m² at the rate of Rs60/m² is Rs 51000.
