Give an example in which you need to find the perimeter of a real-life object.

you are building a fence for your dog and it needs to be a square. One side is 20 ft long. What is the perimeter of the fenced area?

Step-by-step explanation:

The answer would be 80 ft long since it is a square and all sides are equal so you would just add 20 ft 4 times. hope this helped :)

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3
