Answer» 86 m Step-by-step EXPLANATION:=>Area of RECTANGULAR PLOT =460m²=>Length of the plot is 15% more than it's breadth. To find:- =>Perimeter of the plot Solution:- =>Let the breadth of the plot be x =>Then, length of the plot=15% of x =>15x/100 =>3x/20 =>x+3x/20=>23x/20 =>Area of a rectangle=Length×Breadth =>23x/20×x=460 =>23x²/20=460 =>x²=460×20/23 =>x²=400 =>x=20 =>THUS, breadth of the plot is 20m =>And length=23×20/20=23m =>Perimeter of a rectangle=2(l+b) =>2(20+23) =>2×43 =>86m Thus, perimeter of the plot is 86m.Mark me Brainliest!! |
