Question

A floor measuring 7 m by 2.8 m I to be covered with tile measuring 35 cm square how many tiles in used

Answer 1

Given :

• Dimensions of a floor :-
• Length of the floor = 7 m
• Breadth of the floor = 2.8 m
• Dimensions of the tile :-
• Side of the tile = 35 cm

To find :

• Number of Tiles to be used for the floor

Solution :

Firstly, we will find the area of the floor by using the formula of area of rectangle.

Area of rectangle = l × b

where,

• l = length of the rectangle
• b = breadth of the rectangle

Substituting the given values,

⇒ Area = 7 × 2.8

⇒ Area = 19.6

Area of the floor = 19.6 m²

Now, we will find the area of the tile by using the formula of area of square.

Area of square = side²

Substituting the given value,

⇒ Area = (35)²

⇒ Area = 1225

Area of tiles = 1225 cm²

Convert the area of tiles from cm² into m².

As we know,

❖ 1 cm² = 0.0001 m²

To convert the value from cm² into m², divide the value by 10000.

⇒ 1225/10000

⇒ 0.1225 m²

Area of the tiles = 0.1225 m²

Now to find the number of tiles divide the area of floor by area of tiles.

No. of tiles = Area of floor/Area of tiles

Substituting the given values,

⇒ No. of tiles = 19.6/0.1225

⇒ No. of tiles = 160

Number of tiles required = 160.

Answer 2

${\boxed{\underline{\tt{ \orange{Required \: \: Answer:-}}}}}$

彡GIVEN:-

• Length of Rectangle = 7m

• Breadth of Rectangle = 2.8m

• Side of Square = 0.35m

彡TO FIND:-

• Tiles needed

彡FORMULA USED:-

• Area of square = Side × Side

• Area of Rectangle = Length × Breadth

• $\tt{No. \: \: of \: \: Tiles = \frac{Area \: \: of \: \: Rectangle}{Area \: \: of \: \: Square} }$

彡SOLUTION:-

★Area of square = Side × Side

Area of square = (0.35 × 0.35) sq. m

★Area of Rectangle = Length × Breadth

Area of Rectangle = (7 × 2.8) sq. m

$\tt{No. \: \: of \: \: Tiles = \frac{(7 × 2.8)}{(0.35 × 0.35)} }$

No. of Tiles = 19.6/0.1225

${\boxed{\underline{\pink{\mathbb{Tiles = 160 }}}}}$
