Question

PLEASE EXPLAIN AND HELP?
A garden has width sqrt13 and length 7sqrt13. What is the perimeter of the garden in simplest radical form?

Answer 1

The perimeter is simply all of the sides added together. It helps to draw a picture:

\[\sqrt{13}+7\sqrt{13}+\sqrt{13}+7\sqrt{13}\]
Since they all have the same radicand, you can add them all together.

\[16\sqrt{13}\]
This is the final awnser as you cannot simply further.
