3) The dimensions of your living room are 13 ft. by 16 ft. How many square meters of carpet
mixas84 [53]

Answer:

19.32 m²

Explanation:

The area of a living room is the product of its length and breadth. The area is given by:

Area = length × breadth

1 meter = 3.28 feet. Hence:

Length = 16 ft

16 ft = 16\ ft*\frac{1\ m}{3.28\ ft} =4.88\ m

Breadth = 13 ft

13 ft = 13\ ft*\frac{1\ m}{3.28\ ft} =3.96\ m

Area = length × breadth = 4.88 m × 3.96 m = 19.32 m²

Hence 19.32 m² of carpet is needed for the living room
