Answer:

Total number of tiles required= 5920.

Step-by-step explanation:

Given : Garden is 40 m long and 30 m wide a two meter wide path is to be paved using 25 cm × 20 cm size  

To find : How many such tiles will be required

Solution :  

We have given the length and breadth of the garden 40 m long and 30 m wide.

The area of the garden is  

$A= length \times width$

$A= 40 \times 30$

$A= 1200 m^2$

A two meter wide path is to be paved,

So, the length = 44 m and breadth = 34 m

Area of the pathway is

$A= length \times width$

$A= 44 \times 34$

$A= 1496 m^2$

The area in which tiles is to be paved is

Area = 1496-1200 =296 square meter.

We have given the length and breadth of the tiles 25cm long and 20 cm wide.

Convert cm into m

1m=100cm

1cm=1/100 m

25cm = 0.25 m

20 cm=0.20 m

The area of the tiles is  

$A= length \times width$

$A= 0.25 \times 0.20$

$A= 0.05 m^2$

Number of tiles = Total area / area of tiles

$T= \frac{296}{0.05}=5920$

Therefore, Total number of tiles required= 5920.
