Question

3. A tablecover 5 m x 3 m, is spread on a meeting table. If 25 cm of the table cover is
hanging all around the table, find the area of the table top.


​

Answer 1

Answer:

Answer

Length = 5 cm = 500 cm 

Breath = 3 cm = 300 cm

(hanging) Extra Table cover = 25 cm

∴ Length of top= 500 - 25cm =475

Breadth of top= 300 - 25 =375

Area of top = l×b

=475×375

=178125cm

Answer 2

Given:

• Tablecover of table = 5m × 3m
• Extra Table Cover = 25 cm

• Length (l) = 5m
• Breadth (b) = 3m

To Find

• Find the area of the table top..?

Solution:

$\huge{ \circ }$ Length of the tablecover :-

:: 1 m = 100 cm

5m = 500 cm

$\huge{ \circ }$ Breadth of the tablecover :-

:: 1m = 100 cm

3m = 300 cm

We have to Find length of Tablecover without of Extra Hanging Table Cover,

Length (l) of Tablecover = (500 - 50)cm

$\colon\implies$ 450 cm

Breadth (b) of Tablecover = (300 - 50)cm

$\colon\implies$ 250 cm

Now, We can find the exact Area of the Table top :-

$\circ {\boxed{\tt\green{ Area_{(Rectangle)} = Length_{(l)} \times Breadth_{(l)} }}}$

Putting values,

$\colon\implies{\tt{ l \times b }} \\ \\ \\ \colon\implies{\tt{ 450 \times 250 }} \\ \\ \\ \colon\implies{\tt{ 112500 \ cm^2 }}$

Hence,

• The Area of Table Top is 112500 cm² .

$\huge{ \circ }$ We can Convert Area into m² as:

1 m² = 10000 cm²

$\colon\implies{\tt{ m^2 = \cancel{ \dfrac{112500}{10000} } }} \\ \\ \colon\implies{\tt{ m^2 = 11.25 }}$

Hence,

• Area of the Table top is 11.25 m²
