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 with the dimensions $20m\times 15m$. A garden is developed around the house.Find the total cost of developing a garden around the house at the rate of 55 per $m^2$.

Answer 1

Side of a square plot = 25 m
$\therefore \text{Area of square plot}=(side{)}^2=(25{)}^2=625m^2$
Length of the house = 20 m and
Breadth of the house = 15 m
$\therefore$ Area of the house = length $\times$ breadth = 20 $\times 15=300m^2$

Area of garden = Area of square plot - Area of house
$625-300=325m^2$
Cost of developing the garden per sq.m = Rs 55
Cost of developing the garden 325 sq.m = Rs 55 $\times$ 325 = Rs 17,875
Hence total cost of developing a garden around in Rs 17,875.
