the area of a rectangular plot is 460 square metres . if the length is 15 % more than the breadth , what is the breadth of the plot ?
"lb = 460 m 2 let breath = b l = b * ( 100 + 15 ) / 100 = 115 b / 100 from these 115 b / 100 * b = 460 b 2 = 46000 / 115 = 400 b = root of 400 = 20 m answer b"
sqrt(divide(460, subtract(const_1, divide(15, const_100))))
