Question
A rectangular floor has a length of 25 metres and
perimeter of 78 metres. If the entire floor is to be carpeted at a cost of Rs. 8 per m2, then find the cost of carpeting the floor.Solution
Let the breadth of the floor = 'b' metresThen, perimeter of the floor = 2 X (25 + b) = 78So, b = (78/2) - 25 = 14So, area of the floor = 25 X 14 = 350 m2So, cost of carpeting the floor = 350 X 8 = Rs. 2800
