a rectangular grass field is 70 m * 55 m, it has a path of 2.5 m wide all round it on the outside. find the area of the path and the cost of constructing it at rs. 2 per sq m?
multiply(subtract(rectangle_area(add(70, multiply(2.5, 2)), add(55, multiply(2.5, 2))), rectangle_area(70, 55)), 2)
"area = ( l + b + 2 d ) 2 d = ( 70 + 55 + 2.5 * 2 ) 2 * 2.5 = > 650 650 * 2 = rs . 1300 answer : b"
