To find the area of the room, first count the no of horizontal and vertical squares Verticle squares = 9 Horizontal Square =12 so, total no. of squares = 9x12 = 108 since each square is 1 square foot of area so, total area of the room = 108 square feet

Now, no. of verticle squares in frame of bed = 6 and horizontal square = 7 so total no. of squares = 6x7 = 42 so, area of the frame of bed = 42 square feet

And area no. covered by bed = Total area of Room - Area of the frame of bed = 108 -42 = 66 square feet
