Question

What is the correct formula for the perimeter of a rectangle with length (l) and breadth (b)?

पर्याय

• Perimeter = l × b

• Perimeter = 2 × l + b

• Perimeter = 2 × (l + b)

• Perimeter = l + b

Answer 1

Perimeter = 2 × (l + b)

Explanation:

Since opposite sides of a rectangle are equal, the formula is 2 × length + 2 × breadth, which simplifies to 2 × (l + b).
