Answer 1

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

Answer 2

Answer:

let the breath be x cm

perimeter of rectangle = 2x ( l + b)

100 cm = 2x ( 35 + x)

now we will multiply 2 by 35 and x

100= 70+2x

100 - 70 = 2x

30 = 2x

x = 30/2

x = 15 cm

hence the breath is 15 cm

now the area

Area = l x b

= 35 x 15

= 525 cm²
