Given :- Carlo is lying a carpet of the rectangular room. The length of the floor is 9m by 6m. The boarder around the carpet is 1m wide. Find the area of the floor not covered by the carpet.
Answer :-
→ Length of floor = 9 m
→ Breadth of floor = 6 m
so,
→ Area of floor = 9 * 6 = 54 m² .
now,
→ Length of carpet = (9 - 2*border) = 9 - 2*1 = 7 m
→ Breadth = (6 - 2 * border) = 4 m .
then,
→ Area of carpet = 7 * 4 = 28 m².
therefore,
→ Area of floor not covered by carpet = 54 - 28 = 26 m² (Ans.)
