Question

The length of a rectangle is three more than twice its width.Wite an expression for the perimeter. Use the Distributive Property to simplfy.

My whole class cant get that answer plz figure it out so i can get a homework pass.

Answer 1

Ok so when we find perimeter of a rectangle, the formula is always 2l+2w.
So, in this problem we have undefined lengths. We have 2 lengths.
So, we would start with 2l.
Now we have 2 widths. Each width is represented like this 2l+3
Now let's put together our formula.
2l+2(2l+3)
2l+4l+6 is the expression to find perimeter for this shape. Make a good use of your hw pass :)
