Floor tiles are 25 cm squares. How many tiles

will be needed for a rectangular lawn 12 m long

and 10 m wide. Find the total cost at the rate of

8 per tile.

$\boxed{\huge{\red{Solution}}}$

Given:-

----------

Floor tiles are 25 cm squares.

To Find:-

Focal Length &position of image.

$\boxed{\boxed{\huge{Solution}}}$

Length of lawn = 12 m

Breadth of lawn  10 m

Area of lawn = Length * Breadth

                    =12*10

                    =120 square m.

Area of floor tile = 25 square cm

1 cm square = 0.0001 m square

So, 25 square cm =0.0001 *25=0.0025 square m

Number of tiles required to cover the floor =

                                                                     

 =Cost of 1 tile = Rs . 8

Cost of 48000 tiles = 48000*8= Rs.384000

$\boxed{\huge{\red{Answer:-}}}$

Hence  the total cost at the rate of 8rs. Per tile is Rs. 384000

Answer 2

Answer:

Length of lawn = 12 m

Breadth of lawn 10 m

Area of lawn = Length * Breadth

=12*10

=120 square m.

Area of floor tile = 25 square cm

1 cm square = 0.0001 m square

So, 25 square cm =0.0001 *25=0.0025 square m

Number of tiles required to cover the floor =

=Cost of 1 tile = Rs . 8

Cost of 48000 tiles = 48000*8= Rs.384000
