It is given that  perimeter of a rectangular sheet is 100\; cm and length is 35\; cm

Now, we know that

The perimeter of the rectangle is =2(l+b)

\Rightarrow 100 = 2(l+b)

\Rightarrow 100 = 2(35+b)

\Rightarrow 2b = 100-70

\Rightarrow 2 = \frac{30}{2}=15 \ cm

Now, 

Area of rectangle is 

\Rightarrow l \times b = 35 \times 15 = 525 \ cm^2

Therefore, breath and area  of the rectangle are 15cm and 525 \ cm^2 respectively
