Question

A rectangural sheet of paper is 12 1/2cm long and 8 2/3cm wide.find it's perimeter​

Answer 1

Given :

• Length of the rectangular sheet of paper is 12(1/2) cm.
• Breadth (wide) of the rectangular sheet of paper is 8(2/3) cm.

To find :

• Perimeter of the rectangular sheet of paper =?

Formula Used :

• Perimeter of rectangle = 2(length + breadth).

Step-by-step explanation :

It is Given that,

Length = 12(1/2) cm or 25/2 cm.

Breadth = 8(2/3) cm or 26/3 cm.

As We know that,

Perimeter of rectangle = 2 (length + breadth)

Substituting the values in the above formula, we get,

= 2[(25/2) + (26/3)]

= 2(75 + 52/6)

= 2 × 127/6

= 254/6

= 42.34

Therefore, Perimeter of rectangular sheet of paper = 42.34 cm.

Answer 2

Here,

★ Length → $12\frac{1}{2}$ cm.

★ Width → $8\frac{2}{3}$ cm.

To find :—

• Perimeter of the sheet .

We know that,

$\underline{\underline{ \bold{\tt{Perimeter\:\:of\:\:reactangle = 2 ( lenght + width) }}}}$

So, Perimeter of the sheet —

$\bold{2(12 \frac{1}{2} + 8 \frac{2}{3} )}$

$= \bold{2( \frac{25}{2} + \frac{26}{3} )}$

$= \bold{ 2( \frac{75 + 52}{6} )}$

$= \bold{2 \times \frac{127}{6} }$

$= \bold{\frac{127}{3} }$

$= \large \color{blue}{\bold{42\frac{1}{3} \: \: cm. }}$
