Question

If the width of the dining room table is w feet, and the length is 3w - 2 feet, write an

algebraic expression that represents the perimeter of the table.

Answer 1

2(w)+2(3w-2), or, 8w-4

Explanation:

The formula for finding the perimeter is 2w+2L (2*width + 2*length)

So, since we know the width is "w" and the length is "3w-2", we can just substitute those into the equation.

2(w)+2(3w-2)

From there, if needed, you can simplify to:

2w + 6w-4

Add like terms:

8w - 4

Hope that helps.
