GIVEN :-

Dimentions of table cover is 4m , 2m .

25cm of table cover is hanging all around the table.

Cost of polishing the table is 6.25/m².

TO FIND :-

Area of table-top.

Coat of polishing the table.

APPROACH :-

As 25cm of table cover is hanging all around the table , all dimensions of table is 25cm less than that of table cover . Then we will find the area of table . As we find area of the table , we can easily find cost of polishing at 6.25/m².

SOLUTION :-

Dimensions of table cover : l = 4m , b = 2m

Dimension of table :

l = 4m - 25 cm = 3.75m

b = 2m - 25cm = 1.75m

Area of rectangular table

ㅤㅤㅤㅤㅤㅤㅤㅤ→ length×breadth

ㅤㅤㅤㅤㅤㅤㅤㅤ → 3.75 × 1.75

ㅤㅤㅤㅤㅤㅤㅤㅤ → 6.56m²

Hence, area of Dinner Table is 6.56m².

__________________

We know ,

Cost of polishing 1m² → 6.25

So, cost of polishing 6.56m² → 6.25×6.56

ㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤ ㅤㅤ → 41

Hence , cost of polishing the Dinner Table is 41.

Answer 2

Answer:

Potential difference is the difference in the amount of energy that charge carriers have between two points in a circuit. ... A potential difference of one Volt is equal to one Joule of energy being used by one Coulomb of charge when it flows between two points in a circuit.
