Question 366933
If the length of the rectangle is twice the width, and the perimeter of the rectangle is 30 cm, what is the length and width of the rectangle?
------------------
Let the width be "x":
Then the length is "2x":
----
Perimeter = 2(width + length)
30 = 2(x+2x)
30 = 2(3x)
x = 5 cm (width)
2x = 10 cm (length)
