Question

A rectangle sheet of paper 17/5cm and long l6/5 wide,then it's perimeter

Answer 1

Step-by-step explanation:

perimeter of rectangle= 2(length+breath)

2(17/5+16/5)

2(33/5)

66/5

Answer 2

$\setlength{\unitlength}{1cm} \begin{picture}(6,8) \put(2, 2){\line(0,1){2}} \put(2, 2){\line(6,0){2}} \put(4,2){\line(0,2){2}}\put(4, 4){\line( - 1,0){2}} \end{picture}$

Given:

• Length = 17/5cm
• Breadth = 16/5cm

Find:

• Perimeter of Rectangle sheet

Solution:

we, know that

$\sf \to Perimeter \: of \: rectangle = 2(l + b)$

where,

• Length, l = 17/5cm
• Breadth, b = 16/5cm

✏$\sf Perimeter \: of \: rectangle = 2(l + b)$

✏$\sf Perimeter \: of \: rectangle = 2(\frac{17}{5} + \frac{16}{5})$

✏$\sf Perimeter \: of \: rectangle = 2(\frac{17 + 16}{5})$

✏$\sf Perimeter \: of \: rectangle = 2(\frac{33}{5})$

✏$\sf Perimeter \: of \: rectangle = 2 \cancel{(\frac{33}{5})}$

✏$\sf Perimeter \: of \: rectangle = 2 \times 6.6$

✏$\sf Perimeter \: of \: rectangle = 13.12cm$

Hence, Perimeter of Rectangle will be 13.12cm
