perimeter of rectangular sheet = 2(l+b)
100=2 (35+b)
100/2= (35+b)
50= 35+l
l=50-35
l=15cm
area of rectangular sheet=l×b
=35×15
=525cm^2
100=2 (35+b)
100/2= (35+b)
50= 35+l
l=50-35
l=15cm
area of rectangular sheet=l×b
=35×15
=525cm^2

Given
Perimeter of sheet=100 cm
Length is 35 cm
Let breadth of sheet be x cm
Hence
2(35+x)=105 cm
35+x= 50 cm
So x equals 15cm
Now area of sheet = l*b
= 35 *15
=525cmsq
