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
