Answer:
(a)i. Area=72 square feet
ii. Perimeter =34 feet
(b) Baseboard - perimeter
Carpet - area
Step-by-step explanation:
The room is 9ft x 8ft, therefore it is rectangular shaped.
Length=9ft; Breadth=8ft
(a)i. Area of a Rectangle= Length X Breadth
Area of the room=8X9=72 square feet
ii. Perimeter of a Rectangle=2(Length+Breadth)
Perimeter of the room=2(8+9)=2 X 17 =34 feet
(b) A baseboard goes around the edge or boundary of the room, so it has to do with perimeter
A carpet covers the entire floor so it has to do with the area of the room.
