Question

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

Answer 1

Step-by-step explanation:

p=100cm

p=2(l+b)

100=2(35+b)

100=70+2b

b=100-70/2

b=15cm

hope it helps you :)

Answer 2

Given that,

• Perimeter of a rectangular sheet = 100 cm
• Length of a rectangular sheet = 35 cm

We know that

$\rightarrow$ Perimeter of rectangle = 2 (Length + Breadth)

• 100 = 2 (35 + Breadth)
• $\frac{100}{2}$ = 35 + Breadth
• 50 = 35 + Breadth
• 50 - 35 = Breadth
• 15 = Breadth

$\rightarrow$ Area of rectangle = Length × Breadth

• 35 × 15
• 525 cm²

$\therefore$ The area of a rectangular sheet is 525 cm².
