Answer:

\begin{gathered} Breadth \: of \:the \:sheet=15\:cm \\Area = 525\:cm^{2}\end{gathered}

Breadthofthesheet=15cm

Area=525cm

Step-by-step explanation:

Dimensions of the rectangular sheet:

Let length = l cm

breadth = b cm

l = 35 cm ( given )

i)Perimeter = 100\:cmi)Perimeter=100cm

2(l+b)=100⟹2(l+b)=100

2(35+b)=100⟹2(35+b)=100

35+b={100}{2}⟹35+b=

2

100

\implies 35+b=50⟹35+b=50

\implies b = 50-35=15\:cm⟹b=50−35=15cm

ii) Area (A)= l \times bii)Area(A)=l×b

= 35\:cm \times 15\:cm=35cm×15cm

= 525 \:cm^{2}=525cm

Therefore,

\begin{gathered} Breadth \: of \:the \:sheet=15\:cm \\Area = 525\:cm^{2}\end{gathered}

Breadthofthesheet=15cm

Area=525cmsq
