Question

the length of a rectangle is twice the width. The perimeter is 30cm. What is the width of the rectangle?

Answer 1

Answer:

overall answer Width = 5, Length = 10

Step-by-step explanation:

the perimeter of a rectangle is 2L + 2W = P

so the problem is telling you L = 2W  And P = 30.

So your equation would be

2(2W) + 2W = 30

4W + 2W =30

6W = 30

6W/6 = 30/6

W = 5

And L = 2W

L = 2(5)

L = 10
