​

Answer 1

Answer:

15

Step-by-step explanation:

perimeter=2*[length+breadth]

=2*[35+x]=100

=100/2=50

50-35=15

Answer 2

Answer :

• Breadth of rectangular sheet is 15cm
• Area of rectangular sheet is 525cm²

Given :

• Length of rectangular sheet is 35cm
• Perimeter of rectangular sheet is 100cm

To find :

• Breadth of rectangular sheet
• Area of rectangular sheet

Solution :

(1) Breadth :

Given that,

• Length is 35cm
• Perimeter is 100cm

As we know that,

• Perimeter of rectangle = 2(l + b)

where , l is length 35cm , b is breadth and perimeter is 100cm

》Perimeter of rectangle = 2(length + breadth)

》100 = 2(35 + b)

》35 + b = 100/2

》35 + b = 50

》b = 50 - 35

》b = 15cm.

Hence , Breadth of rectangular is 15cm

(2) Area :

As we know that,

• Area of sheet = l × b

where , l is length 35cm and b is breadth 15cm

》Area = length × breadth

》35 × 15

》525cm²

Hence,Area of sheet is 525cm²

• Breadth of rectangular sheet is 15cm
• Area of rectangular sheet is 525cm²

Verification :

As we know that,

• Perimeter of rectangle = 2(length + breadth)

》2(35 + 15)

》2(50)

》100cm
