Question

The length of a rectangular field is 30 more than twice its width. Write an expression in simplest form for the perimeter of the field in terms of its width w.

Answer 1

The length of the field would be Length= 2w+30
(w=Width)
So you would do 2(2w+30)+2w.
Simplifying this would give you:
4w+60+2w
This can be simplified further:
6w+60
I hope this helps!
