Write an expression to represent the perimeter of the figure below. rectangle with 2x-3 and x+2
In-s [12.5K]
Hi there! 

The perimeter is when you add all the sides of a shape. In a rectangle, two sides are the same, and so are the other two. So, if the two sides are 2x-3 and x+2 the expression will be: 

2(2x-3) + 2(x+2) 

If we were to simplify this, it would be 

4x-6+2x+4 
6x-2

Hope this helps!
