Question

# Derive the general rule for the perimeter of the rectangle? ( use l and b for length and breadth of the rectangle respectively)2(l+b)2b2l(l+b)

Solution

## The correct option is A 2(l+b)We know that, rectangle has opposite sides of equal length. ∴ Length of side AB = Length of side CD    Length of side BC = Length of side AD now, perimeter of rectangle = Length of side AB + Length of side BC + Length of side CD + Length of side DA = l+b+l+b = 2l+2b = 2(l+b)
