Please tell me fast as you can

Answer 1

Answer:

The perimeter of a rectangle whose length is 6 1/2cm and breadth 5 3/4cm is 24.5 cm.

Step-by-step explanation:

Given:

Length of rectangle = $6\frac{1}{2} = \frac{13}{2} =6.5$ cm

The breadth of rectangle = $5\frac{3}{4} =\frac{23}{4} = 5.75 cm$

Find: The perimeter of a rectangle

Formula: the perimeter of a rectangle = 2 ( length + breadth)

= 2 ( 6.5 + 5.75)

= 2(12.25)

= 24.5  cm.

So, the perimeter of a rectangle is 24.5 cm.

Answer 2

Answer:

Perimeter of rectangle is  $\frac{49}{2}$ cm or  $24\frac{1}{2}$ cm .

Step-by-step explanation:

To find :  perimeter of a rectangle

Given : length of rectangle is $6 \frac{1}{2}$  cm  i.e. $\frac{13}{2}$ cm and breadth of rectangle is $5\frac{3}{4}$ cm i.e. $\frac{23}{4}$ cm .

Solution :

• According to question we are given that length and breadth of rectangle are  $\frac{13}{2}$ cm and . $\frac{23}{4}$ cm respectively. We have to find perimeter of rectangle .  
• To find perimeter we use following formula -
• Perimeter of rectangle $= 2 ( l + b )$
• Substituting the values we get,

        Perimeter of rectangle =  $2 ( \frac{13}{2} + \frac{23}{4} )$

                                               $= 2 ( \frac{13\times2 }{4} + \frac{23\times 1}{4})\\\\ =2 ( \frac{26 + 23 }{4} )\\\\= 2( \frac{49 }{4} )\\\\= \frac{49}{2} \ cm$
