Question

the length of a rectangle sheet is 12.5 cm and breadth is 3.5 cm. what is the perimeter of the paper

Answer 1

Answer:

2(a+b)

a=12.5cm

b=3.5cm

=2(12.5+3.5)

=2(16)

=2×16

perimeter of the paper =32cm

Answer 2

Answer:

Perimeter of paper is $32\ cm$ .

Step-by-step explanation:

To find : perimeter of paper .

Given :  length of a rectangle sheet is $12.5$ cm and breadth is $3.5$ cm.

Solution :  

• As per given data we know that , length of a rectangle sheet is $12.5$ cm and breadth is $3.5$ cm. We have to find perimeter of paper .  
• To find perimeter we use following formula -
• Area of rectangle $= 2 (l + b )$
• Substituting the values we get,
• Perimeter of paper =  $2 ( 12.5 + 3.5 )$

                                        $= 2 ( 16 )\\=32\ cm$
