Question

Perimeter of a rectangle with length l’ and breadth 'b' is______________​

Answer 1

Explanation:

Given the length of the rectangle = l

the breadth of the rectangle = b

perimeter of the rectangle = sum of length of all sides of the rectangle

= l+ b+ l+ b

=2 l+2 b

=2( l+ b)

∴ perimeter of the rectangle =2( l+ b)

hope it helps
