Answer 2

$\huge\mathtt\red{\underline{\underline{Given:-}}}$

The area of a rectangular sheet is 500 cm.

The length of the sheet is 25 cm.

$\huge\mathtt\red{\underline{\underline{To\:find:-}}}$

Its width=???

$\huge\mathtt\red{\underline{\underline{Concept\:used:-}}}$

Area of rectangle = length × breadth

Perimeter = 2(length + breadth)

$\huge\mathtt\red{\underline{\underline{Solution:-}}}$

Area of rectangle = length × breadth

$= > 500 = 25 \times b \\ = > b = \frac{500}{25} \\ = > b = 20cm$

Perimeter = 2(length + breadth)

$perimeter = 2(25 + 20) \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 2 \times 45 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 90cm$

$\huge\mathtt\red{\underline{\underline{Answer:-}}}$

The width of the rectangle is 20 cm.
