Question 890287
If the perimeter of a rectangle is 120cm. What are its diamensions if its length is twice its width? Thanks abbey
<pre>
Let width be W
Then length = 2W
Since perimeter = 120 cm, then: 2W + 2(2W) = 120
2W + 4W = 120
6W = 120
W, or width = {{{120/6}}}, or {{{highlight_green(highlight_green(20))}}}
Length = 2(20), or {{{highlight_green(highlight_green(40))}}}
