Answer 1

$\huge\mathfrak{\underline{Correct\:Question:}}$

The perimeter of a rectangular sheet is 100 cm. If the length is 35 cm, find its breadth.

___________________________

Given that:-

• Perimeter of rectangular sheet = 100cm

• Length of rectangular sheet = 35cm

To find:-

• Breadth of rectangular sheet.

Answer:-

$\bold{STEP-BY-STEP-EXPLANATION}$

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 = $\boxed{2 (Length + Breadth)}$

100 = 2 (35 + Breadth)

(100/2) = 35 + Breadth

50 – 35 = Breadth

Breadth = 15 cm

Then,

Area of the rectangle = $\boxed{Length × Breadth}$

= 35 × 15

= 525 cm^2

∴Area of the rectangular sheet is 525 cm^2

Answer 2

Question :

The perimeter of a rectangular sheet is 100 cm. If the length is 35 cm, find its breadth.

Solution :

$\underline{\bold{Given :}}$

• The perimeter of the rectangular sheet = 100 cm
• Length of rectangular sheet = 35 cm

$\underline{\bold{To\:Find}}$

• The breadth of rectangular sheet.

Let the breadth of rectangular sheet be x cm.

$\fbox{\pink {Perimeter=2(Length+Breadth)}}$

$\implies Perimeter= 2(Length+Breadth) \\ \implies 100 = 2(35 + x) \\ \implies 100 = 70 + 2x \\ \implies 100 - 70 = 2x \\ \implies 30 = 2x \\ \implies \frac{ 30}{2} = x \\ \implies 15= x \\ \implies x = 15$
