Q.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 $m^{2}$.

Area of plot =  $side^{2}=25^{2}=625m^{2}$

Area of house = $20\times 15=300m^{2}$

Area of garden around house = $625-300=325m^{2}$

the rate = 55 per $m^{2}$.

the total cost of developing a garden around the house= $55\times 325= Rs 17875$
