A room is 4 m long and 3 m 50 cm wide. How many square metres of carpet is needed to cover the floor of the room?
Answer:
Length of the rectangular room = 4 m
Breadth of the rectangular room = 3 m 50 cm = 3 m + 50 cm = 3 m +
m = 3 m + 0.5 m = 3.5 m
Carpet needed = Area of the rectangular room = length
breadth = 4 m
3.5 m = 14 sq m
