Question

7. A tile has the shape of a rectangle
whose length is 24 cm and breadth is 10
cm. How many such tiles are required to
cover a floor of area 480 sq m? *​

Answer 1

The number of tiles required to cover the floor are 20,000.

Explanation:

• We are given that:
• Length of tile = 24 cm = 0.24 m
• Breadth of tile = 10 cm = 0.1 m
• To Find = Total number of tiles to cover floor = ?

Area of rectangle = Length x breadth

Area of rectangle =   l x b  

Area of rectangle   = 0.24 x 0.1 = 0.024 m^2

Area of floor =  480 sq.m  

Now the number of tile = area of floor / area of tile

Number of tiles = 480 / 0.0 24 = 20,000
