Question

a rectangular sheet of paper is 5cm long and 3cm wide find its perimeter ​

Answer 1

Given:-

• Length of the rectangular sheet is 5cm.
• Breadth of the rectangular sheet is 3cm.

⠀

To find:-

• Perimeter of the rectangular sheet.

⠀

Solution:-

• We have a rectangular sheet. In this question, perimeter of rectangle is used.

⠀

${\dag}\:{\underline{\boxed{\sf{\purple{Perimeter_{(Rectangle)} = 2(l + b)}}}}}$

⠀

Here,

• l = length
• b = breadth

⠀

Putting the values,

$\tt\longrightarrow{Perimeter = 2(5 + 3)}$

⠀

$\tt\longrightarrow{Perimeter = 2 \times 8}$

⠀

$\tt\longrightarrow{Perimeter = 16}$

⠀

Hence,

• the perimeter of the rectangular sheet is 16cm.

⠀

$\sf{Area\;of\;Rectangle\;=\;Length\;\times\;Breadth}$

⠀

$\sf{Area\;of\;Square\;=\;(Side)^{2}}$

⠀

$\sf{Area\;of\;Triangle\;=\;\dfrac{1}{2}\;\times\;Base\;\times\;Height}$

⠀

$\sf{Area\;of\;Parallelogram\;=\;Base\;\times\;Height}$

⠀

$\sf{Area\;of\;Circle\;=\;\pi r^{2}}$

$\sf{Perimeter\;of\;Rectangle\;=\;2\;\times\;(Length\;+\;Breadth)}$

⠀

$\sf{Perimeter\;of\; Square\;=\;4\;\times\;(Side)}$

⠀

$\sf{Perimeter\;of\;Circle\;=\;2\pi r}$

Answer 2

Question :-

→ A rectangular sheet of paper is 5cm long and 3cm wide . Find its perimeter ​

Given :-

→ Length of rectangular sheet of paper = 5 cm

→  Breadth of rectangular sheet of paper = 3cm

To Find :-

→ Perimeter of this rectangular sheet of paper

Solution :-

→ As we know that ,

$\huge{\red{{\underline{\underline{Perimeter\:of\:a\:Rectangle\:=\:2(Length+Breadth)}}}}}$

→ By substituting the values :

$\sf Perimeter\;of\;this\;rectangular\;sheet\;=\; 2 (length+breadth)\\\\\longrightarrow 2(5cm +3cm)\\\\\longrightarrow 2 ( 8 cm ) \\\\\longrightarrow 16\;cm$

∴ Perimeter of this rectangular sheet of paper is 16 cm

More to know :

$\sf \longrightarrow Area\;of\;a\;rectangle\;=\; length \times breadth \\\\\longrightarrow Breadth\;when\;area\;and\;length\;are\;given\;=\; \dfrac{Area}{length} \\\\\longrightarrow length\;when\;area\;and\;breadth\;are\;given\;=\; \dfrac{Area}{Breadth}$
