The length of a rectangle is twice its width. The perimeter of the rectangle is 30 cm. What are the length and width? a) Set up the variables: Let represent the width; Then will represent the length. b)What is the equation that represents the above situation? c)solve the equation d)the length and width are?

Step-by-step explanation:

a) Set up the variables:

Let x represent the width; Then 2x will represent the length.

b) What is the equation that represents the above situation?

Use perimeter formula:

As we set up w = x and l = 2x, and we know that the perimeter is 30 cm, we can build an equation by substituting the values we know or set up:

c) solve the equation

d) the length and width are?

1/8 is left? add a bit more info plz

y-y1=m(x-x1)

y-1=1(x-8)
