if the length of a rectangular field is 30 metres more than its breadth and the perimeter of the field is 540 metres , what is the area of the field in square metres ?
let breadth is x then length is 30 + x now the perimeter = 2 ( x + 30 + x ) = 540 solving this we get x = 120 now the area is 120 * 150 = 18000 answer : a
rectangle_area(square_edge_by_perimeter(subtract(540, multiply(30, const_2))), add(square_edge_by_perimeter(subtract(540, multiply(30, const_2))), 30))
