Question

Perimeter of a rectangle having side of length $x$ and breadth $y$ is ___.

• A. $2\times (x+y)$
• B. $x+y$
• C. $x\times y$
• D. $4\times (x+y)$

Answer 1

The correct option is A $2\times (x+y)$

The perimeter of a polygon is sum of lengths of all the sides. In a rectangle, opposite sides are equal. So, the perimeter of a rectangle having sides of length $x$ and breadth $y$ $=x+x+y+y=2\times (x+y)$.
