Question

a room has rectangular floor of size 300 m by 200 m.a square carpet of side 180 mis land in the room.find the area of the floor which is not carpeted.

Answer 1

so area of the room is 300 × 200 = 60000 m²
and area of the carpet is 180 × 180 =32400 m²
so area left = 60000 - 32400 = 27600 m²

Answer 2

length of room = 300 m
breadth of room = 200 m
floor which is not carpeted = 180 m
area = l*b
        =300*200
         = 6000m
          =180*180
            =32400
            =32400 - 6000
           =27600m
