Question

The perimeter of the triangle shown below is

• A. $x$ + $y$
• B. 2$x$ + $y$
• C. $x$ + 2$y$
• D. 2$x$ $-$ $y$

Answer 1

The correct option is B 2$x$ + $y$

The perimeter of a polygon is the sum of the lengths of its sides.
The sides of the given triangle are $x$, $x$ and $y$ units.
Therefore, its perimeter is $x$ + $x$ + $y$, that is, 2$x$ + $y$.
