Question

. The length of a rectangular field is 140 m. If the ratio of the length to the breadth of the field is 5:3 then find the breadth of the field

I need full written answer in copy ​

Answer 1

Given :

• The length of a rectangular field is 140 m.
• The ratio of the length to the breadth of the field is 5:3 .

To Find :

• Breadth of the Field .

Solution :

$\longmapsto\tt{Let\:length\:of\:the\:field\:be=5x}$

$\longmapsto\tt{Let\:breadth\:of\:the\:field\:be=3x}$

As Given that Length of the field is 140 m . So ,

$\longmapsto\tt{5x=140}$

$\longmapsto\tt{x=\cancel\dfrac{140}{5}}$

$\longmapsto\tt{x=28}$

Value of x is 28 .

Therefore :

$\longmapsto\tt{Breadth\:of\:Rectangle=3(28)}$

$\longmapsto\tt{84\:m}$

______________________

• Area of Rectangle = length * breadth
• Perimeter of Rectangle = 2(l+b)
• Area of Sqaure = Side * Side
• Perimeter of Sqaure = 4 * Side
• Area of Triangle = 1/2 * base * height

Answer 2

$\bf \purple{ \diamonds \:Given : }$

• The length of rectangular field is 140 metre.
• The ratio of length to breadth of the rectangular field is 5:3.

$\bf \purple{ \diamonds \:To \: find : }$

• Breadth of the rectangular field .

$\bf \purple{ \diamonds \:Solution : }$

Let length of rectangular field = 5x

Let breadth of rectangular field = 3x

Length of the rectangular field = 140 m [Given]

$\tt\implies \: 5x = 140 \\ \tt\implies \: x = \frac{140}{5} \: \\ \tt\implies \: x = 28 \: \: \: \:$

• Value of x = 28

$\sf\therefore \: Breadth \: of \: rectangular \: field \: = 3x \\ \implies \tt 3 \times 28 = 84 \: m \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$
