Answer 1

Given data : Rohan plans to tile his kitchen floor by red square tiles each side of the tile is 5cm this kitchen is 320cm in length and 150cm on in breadth.

To find : How many tiles will be need ?

Solution : Now, according to given,

→ side of red square tile = 5 cm

Here, we know that, all side of squares are equal in length.

Now, {we need to find area of one square tile}

→ Area of one square tile = ( side )²

→ Area of one square tile = ( 5 )²

→ Area of one square tile = 25 cm²

Let, the kitchen floor is rectangular in shape.

Here, we know, accirding to given

→ Length of kitchen floor = 320 cm

→ Breadth of kitchen floor = 150 cm

Now, {we need to find area of kitchen floor}

→ Area of kitchen floor = Length * Breadth

→ Area of kitchen floor = 320 * 150

→ Area of kitchen floor = 48000 cm²

To find, number of tiles in need

→ Number of tiles in need

= {Area of kitchen floor}/{Area of one square tile}

→ Number of tiles in need = 48000/25

→ Number of tiles in need = 1920

Hence, 1920 red square tiles are in need to tile the floor.
