Question

a floor measuring 7m by 2.8 m is ti be covered with tiles measuring 35cm square. how many tiles will be needed?​

Answer 1

Answer:

$\orange{ \boxed{ \boxed{5600 \: tiles}}}$

Step-by-step explanation:

$\red{ \mathfrak{ \large{Given}}}$

• Length of the floor is 7m = (7×100) cm=700cm
• Breadth of the floor 2.8m =(2.8×100)cm=280cm
• Area of tiles 35cm square.

$\mathfrak{ \underline{ \large{To \: find}}}$

• Number of tiles to cover the floor.

$\purple{ \mathfrak{ \underbrace{ \large{Solution}}}}$

Area of the floor= (Length× Breadth)

= (700×280)cm square

= 196000 cm square.

Hence,the number of tiles are (196000÷35)=5600

Hence,5600 tiles is needed to cover the floor.

Answer 2

Given :

•Length of the floor is 7m = (7×100) cm=700cm

•Breadth of the floor 2.8m =(2.8×100)cm=280cm

•Area of tiles 35cm square.

To find:

Number of tiles to cover the floor.

Solution

Area of the floor= (Length× Breadth)

= (700×280)cm square

= 196000 cm square.

Hence,the number of tiles are (196000÷35)=5600

Hence,5600 tiles is needed to cover the floor.
