Question

Which of the following expression represents the perimeter of the window?​

Answer 1

Answer:

2 ( $2x$ +$x$ )

Step-by-step explanation:

Perimeter of a rectangle= $2 (l+b)$

length= $2x$

breadth= $x$

Perimeter of window= $2 (l+b)$

= 2 ( $2x$ +$x$ )

= 2 ( $3x$ )

= 6$x$

So the expression which represents the perimeter of the window will be          2 ( $2x$ +$x$ )
