Here is your answer.

Length of plot = 14m
Breadth of plot = 12.5m

Area of rectangle = l × b

= 14 × 12.5

$= 175 {m}^{2}$

Now,

(1m = 100cm)

Length of tiles = 10cm.

= 0.1m

Breadth of tiles = 7cm

= 0.07m

Area of tiles = 0.1 × 0.07

$= 0.007m {}^{2}$
Now,

Number of tiles required = Area of plot \ Area of tiles

$= \frac{175}{0.007} \\ \\ = 25000$
Therefore, 25,000 tiles are required.

Cost per hundred tiles = Rs. 70

$= \frac{25000 \times 70}{100} \\ \\ = 17500$
Therefore, Rs. 17,500 is required.
