Question

The perimeter of a rectangular sheet is 200cm. If the length is 35cm, find its breadth. Also find its area.

Answer 1

Answer:

${\tt{\red{\underline{\underline{\huge{Given:}}}}}}$

• Perimeter = 200cm
• Length = 35cm
• Breadth = b

Finding the Breadth-:

• Perimeter = 2 × (L+B)
• 200 cm = 2 × (35 + b)
• (35 + b) = 200/2
• (35 + b) = 100
• b = 100-35
• b = 65 cm

Now, Finding the Area-:

• Area = L × B
• Area = (65 cm × 35 cm)
• A = 2275 cm²

Answer 2

Answer:

$\rightarrow$ Length= 65 cm

$\rightarrow$ Area = ${2275\:cm}^{2}$

Step-by-step explanation:

Correct question- The perimeter of a rectangular sheet is 200cm. If the breadth is 35cm, find its length . Also find its area.

ㅤ

Finding Length-

$\color{black}\boxed{\colorbox{saffron}{Perimeter-2(length+breadth) }}$

$200 = 2(35 + x) \\ \\ = 200 = 70 + 2x \\ \\ 200 - 70 = 2x \\ \\ 130 = 2x \\ \\ \frac{130}{2} = x \\ \\ 65 = x$

So,length = 65 cm

ㅤ

Finding Area-

$\color{black}\boxed{\colorbox{saffron}{Area - length×breadth}}$

$65 \times 35 \\ \\ = {2,275 \: cm}^{2}$

Answer obtained respectively.
