Perimeter of rectangle=2(l+b).
100=2(35+b)
100/2=35+b
50=35+b
b=15
Area =l×b
=35×15
=525.
100=2(35+b)
100/2=35+b
50=35+b
b=15
Area =l×b
=35×15
=525.

The length =35cm
The perimeter =100cm
Let breadth be b.
Perimeter of rectangular sheet=2(l+b)
100cm=2(35cm+b)
100cm/2=35cm+b
50cm=35cm+b
50cm-35cm=b
15cm=b
Now we will find area
Area of rectangular sheet=l×b
35cm×15cm
525cm2(cm square)
The area is 525cm2 & breadth is 15cm.
Hope u like it pl vote.
Thank you
