Question

If a rectangle has a length of 4x and a width of x+5 what is the perimeter?

Answer 1

10x + 10 units

Explanation:

To find the perimeter of a rectangle, you can simply add up the length and width, and then multiply that sum by 2. The sum of the dimensions is 4x + (x + 5) = 5x + 5 and two times that would then be 2(5x + 5) = 10x + 10.
