find breart​

Answer 1

Appropriate question :

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

• Perimeter of a rectangular field is 50 cm and its length is 15 cm. Find its breadth.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Given :

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

• Perimeter of rectangular field is 50cm.

• Length of the field is 15 cm.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

To find :

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

• It's breadth ?

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Solution :

⠀⠀⠀⠀⠀

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

$\dag\;{\underline{\frak{As\;we\;know\;that,}}}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

$\star\;{\boxed{\sf{\pink{Perimeter_{\;(rectangle)} = 2(l + b)}}}}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

⠀⠀⠀⠀

$\underline{\bigstar\:\boldsymbol{According\:to\:the\:question\::}}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

⠀⠀⠀⠀⠀☯ Let, the breadth be 'b' ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

$:\implies\sf 2(15 + b) = 50$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

⠀⠀⠀⠀

$:\implies\sf (15 + b) = \cancel\dfrac{50}{2}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

$:\implies\sf 15 + b = 25$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

$:\implies\sf b = 25 - 15$⠀⠀

⠀

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

$:\implies{\underline{\boxed{\frak{\purple{b = 10\:cm}}}}}\;\bigstar$

⠀⠀⠀

$\therefore\:{\underline{\sf{Breadth\:of\:field\:is\: {\textsf{\textbf{10\:cm}}}.}}}$

Answer 2

Correct Question:

• Perimeter of a rectangular field is 50 cm and its length is 15 cm. Find its breadth.

Given:

• Length of rectangular field = 15 cm
• Perimeter of rectangular field = 50 cm

To Find:

• Breadth of the rectangular field.

Solution:

Let the breadth rectangular of the rectangular field be "x".

As we know that,

⋆ Perimeter of rectangle = 2(Length + breadth)

Putting the values,

➜2(15 + x) = 50

➜ (15 + x) = 50/2

➜ 15 + x = 25

➜ x = 25 - 15

➜ x = 10 cm

Hence,

Breadth of rectangular field is 10 cm.
