ANSWER:
From the question it is given that,
Perimeter of the a Rectangular sheet = 100 cm
Length of the Rectangular sheet = 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
Then,
Area of the rectangle = Length × Breadth
= 35 × 15
= 525 cm2
∴Area of the Rectangular sheet is 525 cm2
