Step-by-step explanation:
Perimeter of the rectangular sheet
= 2 × ( l+b )
»» 100 = 2×(35+b)
»» 35+b = 100/2
»» 35+b = 50
»» b = 50-35 = 15 cm
Hence, the breadth of the rectangular sheet is 15 cm.
Also, area of the rectangular sheet
»» l × b
»» 35×15 = 525 cm²
hope it helps you.

Answer:
Breadth is 35 cm
Area=525 cm²
Step-by-step explanation:
perimeter of a rectangular sheet is 100cm.
l=35 cm
We know that Perimeter of the Rectangle = 2 (Length + Breadth)
100 = 2 (35 + Breadth)
100/2 = 35 + Breadth
50 – 35 = Breadth
Breadth = 15 cm
We know that, Area of the rectangle = Length × Breadth
= 35 × 15
= 525 cm²
