the length of a rectangular plot is 10 mtr more than its width . the cost of fencing the plot along its perimeter at the rate of rs . 6.5 mtr is rs . 1950 . the perimeter of the plot is ?
sol . let width = x , length = ( 10 + x ) perimeter = 2 ( x + ( 10 + x ) ) = 2 ( 2 x = 10 ) & 2 ( 2 x + 10 ) * 6.5 = 1950 x = 70 required perimeter = 2 ( 70 + 80 ) = 300 d
multiply(add(divide(subtract(divide(divide(1950, 6.5), const_2), const_10), const_2), add(divide(subtract(divide(divide(1950, 6.5), const_2), const_10), const_2), const_10)), const_2)
