A rectangular carpet was placed in a rectangular floor which is 8m long and 7m wide leaving 1m border all around it. Find the area of the carpet. Find the area of the uncovered part of the floor.?

each of the carpet's dimensions is 2 m less than the floor dimensions
... one m on each end and each side

the area of the floor is ... 8 m * 7 m = ? m^2
