Answer:
perimeter of the sheet = 100 cm
2[l+b] = 100
2 [ 35 + b ] = 100
35 + b = 100 / 2
35 + b =50
b = 50 - 35
b = 15 cm

Answer:
To find breadth---
perimeter of rectangular sheet = 2(l + b)
100 = 2(35 + b)
100 = 70 + 2b
100 - 70 = 2b
30 = 2b
30/2 = b
15cm = b
To find area ----
Area of rectangular sheet = l × b
= 35 × 15
= 525cm²
