There is a narrow rectangular plot reserved for a school, in a city. The length & breadth of the plot are in the ratio 15:7.at the the rate of Rs. 100per metre it will cost Rs. 44000 to fence the plot. What are the dimensions of the plot |

Answer» Step-by-step explanation: Let, the TOTAL cost of fencing plot=Rs..44000. and the rate of fencing =Rs..100/m^2. thus, the area of a plot =total cost of fencing. ÷ rate of fencing.
=> 44000/100 =440m^2. then, their dimension of plot = length=15X and breadth=7x. thus, the aera of plot =440m^2. 15x × 7x =440m^2. 105x^2 =440m^2. x^2=440/105 =88/21=4.19m. x=√4.19 =2.04m. hence, length=15*2.04=30.6m. and breadth=7*2.04=14.28m. proved.... Thanks❤❤❤.follow me.... |
