Consider a rectangle of length 6 cm and breadth 8 cm. Then the perimeter of this rectangle is _____.
28 cm
If l is the length of the rectangle and b is its breadth, then its perimeter is given by:-
P=l+b+l+b=(2×l)+(2×b)
Given l=6 cm and b=8 cm
Then, perimeter of the given rectangle is,
P=(2×6)+(2×8) =12+16=28 cm
