Answer 1

Explanation:

hope, this answer will help

Answer 2

Given area of a Rectanglular sheet is 450 cm².

And the length of Rectanglular sheet is 25 cm.

We have to find Breadth of Rectanglular sheet.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

$\boxed{\bf{\mid{\overline{\underline{\bigstar\: According\: to \: the \: Question :}}}}\mid}$

⠀⠀⠀⠀⠀⠀⠀

☯ Length of Rectanglular sheet = 25 cm

☯ Let's Breadth of Rectanglular sheet be b.

⠀⠀⠀⠀⠀⠀⠀

⋆ Reference of image is shown in diagram

⠀⠀⠀⠀⠀⠀⠀

$\setlength{\unitlength}{1.5cm}\begin{picture}(8,2)\linethickness{0.4mm}\put(7.7,3){\large\sf{A}}\put(7.5,2){\sf{\large{b}}}\put(7.7,1){\large\sf{B}}\put(9.3,0.7){\sf{\large{25 cm}}}\put(11.1,1){\large\sf{C}}\put(11.1,3){\large\sf{D}}\put(8,1){\line(1,0){3}}\put(8,1){\line(0,2){2}}\put(11,1){\line(0,3){2}}\put(8,3){\line(3,0){3}}\end{picture}$

⠀⠀⠀⠀⠀⠀⠀

We have,

Area of Rectanglular sheet = 450 cm²

⠀⠀⠀⠀⠀⠀⠀

We know that,

$\star\;{\boxed{\sf{\pink{Area_{\;(Rectangle)} = l \times b}}}}$

⠀⠀⠀⠀⠀⠀⠀

$\dag\;{\underline{\frak{Putting;values}}}$

⠀⠀⠀⠀⠀⠀⠀

$:\implies\sf 25 \times b = 450$

⠀⠀⠀⠀⠀⠀⠀

$:\implies\sf 25 \times b = 450$

⠀⠀⠀⠀⠀⠀⠀

$:\implies\sf b = \dfrac{450}{25}$

⠀⠀⠀⠀⠀⠀⠀

$:\implies\sf b = \cancel{ \dfrac{450}{25}}$

⠀⠀⠀⠀⠀⠀⠀

$:\implies{\underline{\boxed{\sf{\pink{b = 18\;cm}}}}}\;\bigstar$

⠀⠀⠀⠀⠀⠀⠀

$\therefore$ Hence, Breadth of Rectanglular sheet is 18 cm.

★ More to know:

• Perimeter of Rectangle = 2(l + b)

• Area of Square = side × side

• Perimeter of Square = 4 × side

• Area of Circle = πr²

• Circumference of Circle = 2πr
