Given ::-

• Length of floor = 55m.

• Width of floor = 15m.

• Area of tiles used for paving floor = 5sq.m

To find ::-

• How many marble tiles will be required to pave the floor ?

Solution ::-

• Length of floor = 55 m

• Floor of floor = 15 m

• Area of floor = Length × breadth

⠀⠀⠀⠀⠀⠀⠀⠀⠀= 55 × 15

⠀⠀⠀⠀⠀⠀⠀⠀⠀= 825 ${m}^{2}$

• Area of tiles = 5 ${m}^{2}$ [given]

__________

Required tiles = $\dfrac{Area\: of\: floor}{Area\:of\:tiles}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀= $\dfrac{825}{5}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀= 165 tiles

Therefore , 165 tiles are required to pave the floor

Answer 2

Given data :

• The lenght of floor is 55 m and width is 15 m.

• The area of the marble tile is 5 m².

To find : How many marble tiles will be required to pave the floor ?

Solution : Let, the shape of the floor be rectangular. Hence,

→ Length of rectangular floor = 55 m

→ Breadth of rectangular floor = 15 m

Now, by using formula of area of rectangle,

→ Area of rectangular floor

= length * breadth

→ Area of rectangular floor

= 55 * 15

→ Area of rectangular floor

= 825 m²

According to given, area of marble tiles will be required to pave the floor is 5 m².

Now, to find require marble's to pave the floor,

→ Number of marble's

= {Area of rectangular floor}/{area of marble }

→ Number of marble's = 825/5

→ Number of marble's = 165

Answer : Hence, 165 marble's tiles are required to pave the floor.
