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}.

Answers (1)

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
