Answer:
- Breadth = 6 cm
- Length = 12 cm
Step-by-step explanation:
Given:
- Perimeter of rectangle = 36 cm
To Find:
- What is the breadth of rectangle, if the length is twice the breadth.
Now, according to question
⇒ l = 2b
Now, we know the formula
⇒ Perimeter of rectangle = 2(l + b)
⇒ Perimeter of rectangle = 2(2b + b)
⇒ 36 = 2(3b)
⇒ 18 = 3b
⇒ b = 6 cm
And, l = 2b
⇒ l = 2 × 6
⇒ l = 12 cm
