Question

The length of a rectangle is twice its width.

If the perimeter of the rectangle is 36 m, find its length and width.

Answer 1

Length: 12, Width: 6

Explanation:

The width, or w is 1/2 the length, so the length is 2w

So, we can set up the equation 2w+2w+w+w, or 6w=36

So, w=6, and you can plug into the length
