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?

step-by-step explanation:

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing
