Dear Sam ,

How are you ? I am fine over here and I hope the same with you dear . How are your Mom and Dad ? How are you studying ? This letter is about my plans after this board examination of class eleven .

By the end of this month we are going to complete our class eleven board examinations so I decided to discuss some of my plans with you for the holidays which we get for a month . Firstly , I am thinking to come to Hyderabad to meet you and spend some days with you . Let's chill up around and then I'll take you up to Goa and we are going to enjoy there too . This is for the first fifteen days . Later I decided to join a nice coaching centre and entirely concentrate on my studies without getting deviated because Class 12 is so difficult . I decided to enjoy a bit and study a bit .

How are my plans for the holidays ? What about you have you planned anything yet ? If not don't worry I already planned for your first 15 days dear . This time I wish to work hard for class 12 . Send your response about this as soon as possible . All the best for the Boards and don't forget the fruit of hardwork is always sweeter . Work hard for the board examinations later we can chill up together !! Convey my regards to your Mom and Dad dear !! Don't forget to send me a letter back !

With Love ,

Answer 2

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.
