Question

How many square tiles of side 40 cm are needed to build the floor of a room of length 16 mand breadth 10 m ?​

Answer 1

Answer:

1600× 1000 ÷ 40×40= 1000 square tiles

Answer 2

160000 square tiles of side 40 cm are needed to build the floor of a room of length 16 m and breadth 10 m

Step-by-step explanation:

Length of floor = 16 m = 1600 cm

Breadth of floor = 10 m = 1000 cm

Area of floor = $Length \times Breadth = 1600 \times 1000 = 1600000 cm^2$

Side of square tile = 40 cm

Area of square tile = $Side^2 = 40^2 = 1600 cm^2$

No. of square tiles required = $\frac{1600000}{1600}=16000$

Hence 160000 square tiles of side 40 cm are needed to build the floor of a room of length 16 m and breadth 10 m
