Answer:

The answer is D: 2 x 60 + 2 x 30

Step-by-step explanation:

The perimeter is the lengths of all the sides of a shape combined.  Therefore, 60 is one side and 30 is the other side.  Since the opposite sides are equal, there are two sides that equal 60 and two sides that equal 30.  

So, 60 + 60 + 30 + 30.  

60 + 60 = 60 x 2

30 + 30 = 30 x 2

Therefore, the answer is 60 x 2 + 30 x 2.

<span>Put up a graph or a chart, and suddenly everything you're saying makes sense! Graphs or charts help people understand data quickly. Whether you want to make a comparison, show a relationship, or highlight a trend, they help your audience "see" what you are talking about.

Hope this helps.
