Question :-

How many tiles whose Length and Breadth are 12 cm and 5 cm respectively will be needed to fit in a rectangular region whose Length and Breadth are respectively:

Answer the question step by step

Answer 1

Answer:

(a) Area of region = 100 cm x 144 cm = 14400 cm.sq

Area of one tile = 5 cm x 12 cm = 60 cm.sq

Number of tiles = \frac{Area\ of\ region}{Area\ of\ one\ tile}

Area of one tile

Area of region

= 240

Thus, 240 tiles are required.

(b) Area of region = 70 cm x 36 cm = 2520 cm.sq

Area of one tile = 5 cm x 12 cm = 60 cm.sq

Number of tiles = \frac{Area\ of\ region}{Area\ of\ one\ tile}

Area of one tile

Area of region

= 42

Thus, 42 tiles are required.

Answer 2

$\Large\tt\underbrace{Answer}$

So, here we have to find the number of tiles want to fitted in 2 rooms. So, let's call that 2 room as room a and room b.

• To find the required tiles for the room let's find the area of one tile and area of room a.

So, Area of one tile = l × b

Area = 12 × 5 = 60

$\large\sf\orange{Area\:of\:one\:tile\:is\:60cm²}$

Now, We want to find the area of room a.

Area of room a = l × b

Area = 150 × 162 = 24,300

$\large\sf\orange{Area\:of\:room\:a\:is\:24,300²}$

Now, We want to find the number of tiles which can be fitted in room a.

The formula for finding number of tile is $\downarrow$

Number of tiles needed = $\Large\frac{Area\:of\:region}{Area\:of\:one\:tile}$

Number of tiles needed = $\Large\frac{24,300}{60}$

$\large\sf\orange{•°•\:Tiles\:needed\:for\:room\:a\:is\:405\:tiles.}$

_________________________________________

Now, We want to calculate the tiles needed in room b.

As, we did earlier find the area of tile and region then divide it.

So, Answer is $\downarrow$

Area of tile = 60m² (As we did earlier)

Area of region = l × b

Area = 80 × 42 = 3,360

$\large\sf\orange{Area\:of\:room\:b\:is\:3,360²}$

Now tiles needed in room b = $\Large\frac{Area\:of\:region}{Area\:of\:one\:tile}$

Number of tiles needed = $\Large\frac{3,360}{60}$

$\large\sf\orange{•°•\:Tiles\:needed\:for\:room\:b\:is\:56\:tiles.}$

__________________________________________

In short room a need $\large\sf{405\:tiles}$

Room b need $\large\sf{56\:tiles}$
