a rectangular courtyard , the sides of which are in the ratio of 4 : 3 , cost rs . 600 for paving at 50 p per m 2 ; find the length of the diagonal of the courtyard ?
1 m 2 - - - - 1 / 2 ? - - - - - 600 = > 1200 m 2 4 x * 3 x = 1200 = > x = 10 answer : b
subtract(sqrt(add(power(multiply(4, sqrt(divide(divide(600, divide(50, const_100)), multiply(4, 3)))), 2), power(multiply(3, sqrt(divide(divide(600, divide(50, const_100)), multiply(4, 3)))), 2))), add(const_2, const_3))
