            =576cm2

2. Length of the room = 7 m Breadth of the room = 4 m 25 cm = 4.25 m 

Area of the floor of the room = length x breadth                                       

       = 7 × 4.25                                           

   = 29.75 sq m 

Area of the carpet needed = 29.75 sq m.

area = s*s

3.2*3.2=10.25

so mica per squar meter cost =50 rupees

cost = area of square * cost
