Question

How many square tiles of length 25cm can fit in square room of side 5m ?

Answer 1

Answer:

Number of tiles = 400

Explanation:

Square tiles of length = 25cm

Area of tiles = 25² = 625 cm²

Square room of side =  5m = 500 cm

Area of room = 500² = 250000 cm²

Number of tiles = 250000/625

$=\frac{250000}{625} \\=400$

Area :

The space occupied by a two-dimensional figure is its area. In other words, it is the indicates that determines how many unit squares are present on the surface of a closed figure. It is typically measured in square units like square inches, square feet, etc. Area is used to compute the area encircled by different geometric figures.  For example, a cone is a circular, three-dimensional shape. This shows that the base is composed of a radius. The height of the cone is measured to determine the distance between the base's centre and its highest point.

The number of square tiles required = 400

Given :

A square room of side 5m

To find :

The number of square tiles of length 25cm can fit in square room of side 5m

Formula Used :

For square of side a unit

The area of the square = a² sq.unit

Solution :

Step 1 of 3 :

Calculate area of the square room

Side of the square room = 5 m = 500 cm

∴ Area of the square room

= 500² cm²

= 250000 cm²

Step 2 of 3 :

Calculate area of each sqruare tiles

Side of each sqruare tile = 25 cm

∴ Area of each sqruare tiles

= 25² cm²

= 625 cm²

Step 3 of 3 :

Calculate the number of square tiles required

The number of square tiles required

$\displaystyle \sf = \frac{Area \: of \: the \: square \: room}{ Area \: of \: each \: sqruare \: tiles}$

$\displaystyle \sf = \frac{250000}{625}$

$= 400$
