Answer 1

Area of Rectangular Sheet = 500cm²

Length of Rectangle Sheet = 25cm

Let the Breadth = x

___________________________

Area of Rectangle = ${ l ×b }$

Breadth = $\sf\dfrac{Area}{Length}$

= $\dfrac{500}{25}$ = 20cm

Hence, The Breadth is 20cm

____________________________

Perimter = 2 × (Length + Breadth)

Length of Rectangle Sheet = 25cm

Breadth of Rectangle Sheet = 20cm

Perimter of Rectangle Sheet = 2 × (25 +20)

= 2 × 45

= 90 cm

hєncє, thє pєrímєtєr íѕ 90cm

Answer 2

$\huge\boxed{ \bf \: Answer}$

Area of the rectangle sheet = 500cm²

Length (L) = 25cm .

Area of the rectangle = Length × breadth (where b = width of the sheet)

❄︎ Therefore,width b = $\dfrac{Area}{L}$= $\dfrac{500}{25}$=20Cm.

Perimeter of sheet = 2 × (L+B) = 2 × (25+20)cm = 90cm .

So,the width of the rectangular sheet is 20cm and its perimeter is 90cm.
